What Did Yeshua Mean by “Fulfill”?
Matthew 5:17–20, “Not One Jot or Tittle,” and the Law and the Prophets in the Kingdom of Heaven
A Guided Topical Bible Study
Primary passages Matthew 3:13–17; Matthew 5:17–48; Matthew 7:12; Matthew 11:13; Matthew 19:1–9; Matthew 22:34–40; Matthew 23:23; Matthew 24:35; Matthew 26:52–56; Matthew 28:18–20; Luke 16:16–17; Luke 24:44–47; Jeremiah 31:31–34; Deuteronomy 6:4–9; Leviticus 19:18
Before We Begin
Pull up a chair. I have coffee, and this is one of those studies where I want us to move slowly because one English word has been asked to carry an enormous amount of theology.
That word is fulfill.
Yeshua says in Matthew 5:17, “Do not think that I came to abolish the Law or the Prophets. I did not come to abolish but to fulfill.” From that one sentence, Christians have reached almost opposite conclusions. One person says, “There it is. Jesus fulfilled the Law, so we do not have to.” Another says, “Fulfill means He obeyed Torah perfectly, so absolutely nothing about Torah changed.” Someone else says the Law ended at the cross. Another insists Yeshua only corrected Pharisaic traditions and never altered anything Moses said. Then somebody brings up the dictionary definition of fulfill, somebody else brings up “jot and tittle,” and before long five different doctrines are standing on one Greek verb while the next three verses are sitting there waving their hands asking whether anybody plans to read them.
So that is exactly what we are going to do. We are going to read them.
I do not want to ask only, “What can the Greek word fulfill mean?” A dictionary can give us a range of possibilities, but context tells us which possibilities fit. We need to ask what Matthew means by the word, what Yeshua contrasts it with, what He says immediately afterward, and what He then does with Torah throughout the rest of the Sermon on the Mount. We also need to let Matthew’s Gospel teach us how Matthew himself uses the language of fulfillment before we allow later theology to define it for him.
At the same time, we need to resist an easy answer from the Torah-observant side. Yeshua does more than merely repeat Moses. He speaks with staggering authority. He reaches beneath outward behavior into anger, lust, motives, truthfulness, retaliation, enemy-love, and the human heart. In some places He appears to move beyond Mosaic concessions or change how a Mosaic provision is applied within the kingdom He is announcing. If our explanation of fulfill means Yeshua changes absolutely nothing, the rest of Matthew 5 is going to make us uncomfortable.
Good.
That is exactly where I want us.
We are not trying to protect a position. We are trying to hear Yeshua.
When Yeshua says He came to “fulfill” the Law and the Prophets, what do you think that means?

Keep those answers. We are coming back to them.
Read the Whole Paragraph First
Before we pull one Greek word apart, open Matthew 5:17–20 and read all four verses together. Please do not stop after verse 17. That is how we get into trouble.
Yeshua says He did not come to abolish the Law or the Prophets but to fulfill them. Then He says that until heaven and earth pass away, not the smallest letter or stroke will pass from the Law until all comes to pass. Then He warns that whoever loosens even one of the least commandments and teaches others to do likewise will be called least in the kingdom, while whoever does and teaches them will be called great. Then He says the righteousness of His disciples must exceed that of the scribes and Pharisees.
That is one argument, not four unrelated sayings.
Whatever fulfill means, it has to make sense beside verses 18, 19, and 20. If my definition of fulfill makes verse 18 sound ridiculous, I probably have the wrong definition. If my definition makes verse 19 reverse verse 17, I have a problem. If my definition turns kingdom righteousness into freedom from righteousness, verse 20 is going to object.
So write this somewhere in your notes:
Matthew 5:17–20 interprets Matthew 5:17.
That is where we begin.
What Does “The Law and the Prophets” Mean?
Yeshua does not say only, “I came to fulfill the Law.” He says, “the Law or the Prophets.” That matters because in Matthew, “the Law and the Prophets” functions as a broad way of referring to Israel’s Scriptures and divine revelation. Matthew uses the pairing later when Yeshua says the Golden Rule sums up “the Law and the Prophets,” and again when He says all the Law and the Prophets hang upon love for Yehovah and love for neighbor.
That immediately makes Yeshua’s statement larger than, “I personally kept all the rules.” His perfect obedience is certainly part of the story, but prophets contain promises, warnings, messianic expectations, covenant hope, and the unfolding story of Israel. Torah itself contains instruction, narrative, covenant, priesthood, sacrifice, patterns, promises, and expectations that point beyond themselves.
If Yeshua fulfills the Law and the Prophets, His claim reaches beyond merely checking commandments off a list. The whole scriptural story is coming to some kind of realization in Him.
That should make us cautious of two simplistic definitions. “Fulfill means obey” is probably too small. “Fulfill means abolish” directly contradicts the word Yeshua just rejected.
We need something richer.
First Word: Abolish
Now look closely at Matthew 5:17. The Greek verb translated abolish, destroy, or do away with is:
καταλύω — kataluō
The word can carry the idea of tearing down, demolishing, destroying, overthrowing, or dissolving something. In this context, Yeshua is denying that His mission is to dismantle or nullify the Law and the Prophets.
And notice how He begins:
“Do not think...”
That tells me He knows His teaching could be misunderstood. People could hear the Kingdom announcement, hear His authority, hear what He is about to say, and conclude that His arrival means Moses and the Prophets are now being discarded.
Yeshua tells them not to think that.
Do not think My arrival means I am here to tear down the Scriptures Yehovah gave. Do not think kingdom teaching means Moses and the Prophets were a mistake. Do not think My authority stands against My Father’s revelation.
That warning comes before the famous “You have heard... but I say” sections.
The order matters.
Then What Does “Fulfill” Mean?
The Greek word is:
πληρόω — plēroō
In Matthew 5:17, the form is plērōsai. The word can carry a range of meaning involving filling, making full, completing, bringing into effect, bringing to realization, or carrying something toward its intended accomplishment.
This is where we have to be disciplined. A Greek word is not a theological vending machine. We cannot insert plēroō, press a button, and expect the entire Law-versus-grace debate to fall out.
Context decides.
But the basic picture is not destruction. It is fullness. Realization. Completion in the sense of bringing something to what it was pointing toward or intended to become.
That gives us a much better question than, “Did Yeshua keep the Law or end the Law?”
The better question may be:
What does Torah look like when its intention reaches fullness in the Messiah?
Now we are getting somewhere.
Matthew Already Used This Word Before the Sermon
Matthew does not wait until chapter 5 to introduce plēroō. He has already been using the language of fulfillment throughout the opening chapters of the Gospel. Again and again, events in Yeshua’s life happen so that Scripture might be fulfilled. Matthew presents Yeshua’s story as Israel’s Scriptures coming to realization.
The same verb also appears in Matthew 3:15 when Yeshua tells John that His baptism is fitting in order to “fulfill all righteousness.”
Think about that sentence for a moment.
When Yeshua says, “Let us fulfill all righteousness,” does He mean, “Let us abolish righteousness because we completed it”?
Of course not.
The word does not inherently mean, “Do this so nobody ever has to care about it again.” That sounds obvious when we say it plainly, but sometimes that is very close to how Matthew 5:17 is explained.
Yeshua fulfills righteousness by carrying out what righteousness requires. Scripture is fulfilled when what Yehovah revealed comes into realization. So when the same Gospel says Yeshua fulfills the Law and Prophets, we should at least allow Matthew’s own usage to guide us before importing a definition from somewhere else.
Fulfilled Prophecy Does Not Mean False Prophecy
Here is a simple illustration. Matthew repeatedly tells us that prophetic Scripture is fulfilled in Yeshua. Once a prophecy is fulfilled, does that mean the prophecy was abolished because it came true?
No.
It means the prophecy reached its intended realization. Its truth was established, not negated.
Now, laws are not identical to predictions. We should not pretend every command functions exactly like prophecy. But remember what Yeshua actually says: He fulfills the Law and the Prophets.
His statement is wide enough to include instruction, promise, prophecy, covenant story, righteousness, and Israel’s hope.
That is why “fulfilled means ended” feels too thin. It notices completion but misses realization.
But “Fulfill” Cannot Mean “Nothing Changes”
Now I want to challenge us from the other direction. If we are Torah-observant, it can be tempting to say, “See? Fulfill just means Yeshua correctly obeyed Torah. End of discussion.”
Not so fast.
Yeshua certainly obeyed Torah, but Matthew presents Him as much more than the best Torah student in the room. He is Messiah, Son, King, Lord, and the One who speaks with an authority that causes the crowds to marvel. He repeatedly says, “But I say to you.” At the end of Matthew, He claims all authority in heaven and on earth.
And the New Covenant He mediates genuinely changes covenant administration. We have already studied the changed priesthood, sacrifice, sanctuary, and mediation. So fulfill cannot reasonably mean, “Everything remains covenantally identical after Yeshua.”
That would erase too much Scripture too.
Our answer has to preserve both truths: Yeshua does not abolish the Law and the Prophets, and Yeshua brings the Law and the Prophets into their Messiah-centered fullness.
That fullness can include continuity and transformation at the same time.
“Until Heaven and Earth Pass Away”
Now read Matthew 5:18 slowly. Yeshua says that until heaven and earth pass away, not one iota or one small stroke will pass from the Law until all comes to pass.
That is strong language.
The iota is the smallest Greek letter and corresponds conceptually to the tiny Hebrew yod. The keraia refers to a small stroke or projection that distinguishes written letters. Yeshua reaches for the smallest imaginable detail of writing.
In plain English, He is saying: do not imagine I mean Scripture becomes disposable. Not even the tiny stuff is casually brushed aside.
Then notice the time language: until heaven and earth pass away.
That sounds considerably larger than, “until Friday afternoon when I die.”
Some interpreters understand the second clause—“until all comes to pass”—as referring especially to the completion of Scripture’s purpose in Yeshua. Others understand the parallel with heaven and earth to push the horizon toward the final consummation. The exact relationship between the two “until” statements is debated.
What I do not think we can do responsibly is wave away verse 18 as though Yeshua obviously means, “This all expires during My earthly ministry.”
The wording is stronger than that.
Verse 18 Does Not Repeat the Same Greek Word
This is one of those details that makes me stop and say, “Okay, wait. Read that again.”
Some English translations make Matthew 5:18 sound as though Yeshua simply repeats the word from verse 17. Verse 17 says, “I came to fulfill.” Verse 18 may read, “until all is fulfilled.” So an English reader naturally assumes Yeshua uses the same Greek verb twice.
He does not.
Verse 17 uses:
πληρόω — plēroō
Verse 18 says:
ἕως ἂν πάντα γένηται — heōs an panta genētai
The verb comes from γίνομαι — ginomai, meaning to happen, come about, or come to pass.
That does not magically solve Matthew 5:18. But it does stop us from building a circular argument on an English translation.
Yeshua does not literally say, “I fulfill the Law, and then the Law passes when I fulfill it.”
That is an interpretation.
The actual Greek deserves more care.
Read Matthew 5:17–18 again. What are the two “until” statements?
________________________________________________________________________________
How does the difference between plēroō in verse 17 and ginomai in verse 18 affect your understanding?
________________________________________________________________________________
Then Yeshua Says Something Even More Awkward
Now read verse 19.
It begins with an important word:
Therefore.
That means verse 19 follows from what Yeshua has just said. Whatever He means by not abolishing, fulfilling, and the Law not passing leads directly into a warning about commandments.
Yeshua warns against someone who breaks, loosens, relaxes, or sets aside one of the least commandments and teaches others to do the same.
The Greek verb is:
λύω — lyō
It means to loose, untie, dissolve, release, or set aside.
And here is another detail the English can hide. The word Yeshua used in verse 17 for abolish is kataluō, a compound built from the same basic luō root. Yeshua says He did not come to tear down or loosen away the Law and Prophets, then immediately warns His disciples against loosening even a least commandment.
Sit with that for a moment.
The flow is not:
“I did not abolish Torah. I fulfilled it. Therefore please abolish the small commandments for Me.”
That would be bizarre.
The therefore matters.
Which Commandments Are “These Commandments”?
Now we reach a real interpretive question. When Yeshua says, “one of the least of these commandments,” what commandments does He mean?
The most natural immediate reading is that He is referring to commandments of the Law He has just been discussing. That is why many interpreters understand verse 19 as a strong affirmation of Torah’s authority. The language of lighter and weightier commands also fits Jewish ways of speaking about commandments.
Another interpretation argues that “these commandments” refers to the kingdom instructions Yeshua is about to give throughout the Sermon on the Mount. Under that reading, the emphasis shifts toward His own messianic teaching.
I do not think those possibilities have to be absolute enemies. If Yeshua is the authoritative fulfiller of Torah, then His kingdom commands are His authoritative exposition of what righteousness looks like under the reign of God.
The real question becomes:
Is Yeshua replacing His Father’s instruction with an unrelated moral system, or bringing that instruction into its intended kingdom fullness under His own authority?
The rest of the sermon will help us answer.
“Unless Your Righteousness Exceeds...”
Then comes Matthew 5:20. Yeshua says His disciples’ righteousness must exceed that of the scribes and Pharisees.
For years, Christians have sometimes heard “Pharisee” as though it simply means “obvious hypocritical villain.” But that makes Yeshua’s statement lose its force. The scribes and Pharisees were known for taking Scripture and religious practice seriously. Yeshua’s audience would not hear, “Be more righteous than people who do not care.”
They would hear a daunting standard.
Yeshua is not lowering the bar.
He is raising it.
But notice how He raises it. He does not merely say, “Keep more rules than they do.” The sections that follow move righteousness inward and outward at the same time. Do not murder becomes a confrontation with anger and contempt. Do not commit adultery reaches into lust. Truthfulness becomes so complete that manipulative oath systems are unnecessary. Justice no longer becomes an excuse for personal revenge. Love stretches all the way to enemies.
This is not less righteousness.
It is righteousness going all the way down.
Now We Reach “You Have Heard... But I Say”
This is where our interpretation of Matthew 5:17 gets tested. Yeshua repeatedly says, “You have heard that it was said...” and then, “But I say to you...”
Some Torah-continuity explanations say Yeshua is only correcting Pharisaic traditions and never addressing Torah itself. That works well in some places, but it is too simple for the whole section. Several of Yeshua’s opening statements directly quote or closely reflect Mosaic Torah.
So we should not protect our conclusion with a slogan.
Let’s walk through them.
“You Shall Not Murder”
Read Matthew 5:21–26. Yeshua begins with the command against murder. He does not say, “Murder is fine now because I fulfilled that command.” He moves deeper.
Anger.
Contempt.
Reconciliation.
The external command prohibited taking innocent life. Yeshua exposes the heart soil from which violence grows. A person can technically avoid homicide while nurturing hatred, contempt, and the dehumanization of another person.
Kingdom righteousness says that is not enough.
Does Yeshua weaken the command against murder, or take it deeper?
________________________________________________________________________________
What does He expose beneath the visible act?
________________________________________________________________________________
This gives us one picture of fulfillment: the command reaches into the heart that produces the action.
“You Shall Not Commit Adultery”
Now read Matthew 5:27–30. Again, Yeshua does not cancel the command. He intensifies its moral reach.
A person can technically avoid physical adultery while cultivating another human being in the imagination as an object for sexual possession. Yeshua goes after the heart.
That is uncomfortable.
Which is probably why we keep trying to turn the Sermon on the Mount into abstract theology instead of letting it examine us.
If fulfill means Torah comes to full expression in the kingdom, this makes sense. Yeshua does not merely police the visible endpoint. He confronts the desire that gives birth to it.
The command gets fuller, not emptier.
Divorce Is Harder
Now read Matthew 5:31–32, then compare Matthew 19:1–9 with Deuteronomy 24:1–4.
This one will not fit neatly into the statement, “Yeshua simply repeats Moses.”
Moses regulates divorce. Yeshua later says Moses permitted divorce because of hardness of heart, then reaches behind Moses to Genesis:
“From the beginning it was not so.”
That is enormously important for understanding fulfillment.
Yeshua does not accuse Moses of wrongdoing. He identifies a covenantal concession operating in a world of hardened hearts, then calls His followers toward the creational intention beneath that concession.
This gives us a category we need. Not every Torah provision expresses creation’s ideal in exactly the same way. Some laws regulate life in a broken world. Yeshua can fulfill Torah by carrying Yehovah’s purpose through the legislation and back toward what it was always protecting.
That is not abolition.
But neither is it simply, “Nothing changes.”
Fulfillment can reveal the destination toward which a covenant provision was moving.
Oaths and Radical Truthfulness
Read Matthew 5:33–37. Torah commands honesty in vows and warns against swearing falsely. Yeshua says, “Do not swear at all. Let your yes be yes and your no be no.”
That sounds more radical, not less.
The point is not that truthful vows were evil. The point is that kingdom truthfulness should be so complete that elaborate verbal systems are unnecessary to distinguish the statements we really mean from the ones we might wiggle out of later.
Think about what that means. If I have to say, “No, seriously, I swear to God this time,” what does that imply about all the other times I speak?
Yeshua is reaching toward undivided integrity.
Again, righteousness is being filled out.
“Eye for Eye” Was Not Permission for Personal Revenge
Now read Matthew 5:38–42.
“Eye for eye, tooth for tooth” comes from Torah, but we need to understand what that principle was doing. The lex talionis principle establishes proportional justice. It limits punishment.
One eye does not justify killing an entire family. One injury does not authorize endless escalating vengeance. The judicial principle restrains retaliation.
Then Yeshua tells His disciples not to run their personal relationships through retaliation.
Turn the other cheek.
Go the second mile.
Give.
That creates a real interpretive challenge. He is not merely saying, “You misunderstood the words eye for eye.” He is moving His disciples from a judicial principle of proportional justice into a kingdom ethic of personal non-retaliation and generosity.
That is another reason the statement “Yeshua only corrects Pharisaic tradition” is too simple.
Something deeper is happening.
Messiah is authoritatively showing what Torah looks like when righteousness reaches its kingdom goal in the lives of His disciples.
“Love Your Enemy”
Now read Matthew 5:43–48.
Torah explicitly commands, “Love your neighbor.” The phrase “hate your enemy” is not a direct quotation from Leviticus 19:18. There are certainly warfare texts, judgments, and distinctions between Israel and enemies in the Scriptures, and people could build a narrow definition of neighbor-love from them.
Yeshua refuses that narrowing.
Love your enemies.
Pray for those who persecute you.
Why?
Because your Father sends sun and rain upon righteous and unrighteous alike.
Then Yeshua brings the section toward a stunning destination: “Be perfect,” or complete, “as your heavenly Father is perfect.”
There is the goal.
The question is no longer, “How little obedience can I technically get away with?”
The question is, “What does it look like to resemble my Father?”
That sounds a lot like fullness.
So What Is Yeshua Doing in These Examples?
Put the sections together and notice that Yeshua does not handle every subject in exactly the same way.
With murder and adultery, He exposes the heart beneath the outward act. With divorce, He reaches behind a Mosaic concession to the creation ideal. With oaths, He calls for truthfulness so complete that oath manipulation becomes unnecessary. With retaliation, He moves disciples beyond personal vengeance even where Torah establishes proportional judicial justice. With enemies, He stretches love beyond the comfortable boundaries people would naturally draw.
So I do not think the best description is, “Yeshua abolished Torah.” The passage begins by denying that.
But I also do not think the best description is, “Yeshua merely repeats Torah exactly as it stood.”
He does not.
He fulfills it.
He brings divine instruction under the authority of Messiah toward its full kingdom intention. That includes interpretation, intensification, embodiment, prophetic realization, recovery of creation purpose, and—in places where covenantal conditions require it—transformation of application.
That is a much richer word than ended.
The Sermon Ends With “Law and Prophets” Again
Now skip ahead to Matthew 7:12. Yeshua gives what we call the Golden Rule: do to others what you would want them to do to you.
Then He says:
“For this is the Law and the Prophets.”
There is our phrase again.
At the beginning of the sermon: do not think I came to abolish the Law and Prophets.
Near the end of the sermon’s ethical teaching: this is the Law and Prophets.
Matthew is framing kingdom righteousness with Israel’s Scriptures. Yeshua is not teaching His disciples how to escape righteousness. He is teaching them what the righteousness toward which Scripture was always moving looks like under the reign of God.
Later Yeshua Summarizes Torah With Torah
Now read Matthew 22:34–40. Yeshua is asked for the greatest commandment.
He answers from Deuteronomy 6: love Yehovah with all your heart, soul, and mind.
Then from Leviticus 19: love your neighbor as yourself.
And what does He say?
All the Law and the Prophets hang on these two.
Notice what He does not say. He does not say, “These two commandments replace all those bad old ones.” He says everything hangs from them.
Love is the organizing principle.
And love is not a vague feeling.
Yeshua gets His definition of love from Torah itself.
The Shema.
Leviticus.
Torah is not competing with love.
Torah teaches covenant love.
Summary Does Not Mean Cancellation
We understand this intuitively in other areas. If I say, “This entire job comes down to serving the customer well,” I am not saying, “Therefore the procedures about protecting customer data, handling money honestly, and doing the job correctly are canceled.”
I am telling you the governing principle that makes the details coherent.
Yeshua says love of Yehovah and neighbor holds the Law and Prophets together.
That is summary.
Priority.
Interpretive center.
Not automatically cancellation.
This matters because people sometimes say, “Jesus replaced all the commandments with love.”
But the two love commandments are Torah commandments.
Yeshua summarized Torah with Torah.
That should slow us down.
Weightier Matters Do Not Make Lighter Matters Nothing
Now read Matthew 23:23. Yeshua rebukes scribes and Pharisees for tithing tiny herbs while neglecting justice, mercy, and faithfulness.
He calls these the weightier matters of the Law.
That means Yeshua recognizes moral weight and priority within Torah. Not every command carries equal significance in exactly the same way.
But then He says something inconvenient for both extremes. The weightier things should have been done without neglecting the others.
That sounds remarkably similar to Matthew 5:19.
Least commandments.
Weightier matters.
Yeshua can distinguish weight without declaring the lighter matter meaningless.
The problem is not careful obedience. The problem is meticulous religion that leaves Yehovah’s heart behind.
You can tithe your herb garden and treat people terribly.
Congratulations.
You counted parsley and missed justice.
Yeshua wants both obedience and proportion.
“Fulfill” Is Not the Same as “Do Away With”
At this point, I want to ask a very simple question. If Yeshua wanted to say, “I came to abolish the Law and Prophets,” could He have said it?
Yes.
In fact, He uses the exact word.
Then denies it.
I cannot make the sentence “I did not come to abolish” mean “I came to abolish by fulfilling” without making the contrast nearly meaningless.
That does not mean fulfillment leaves every covenantal expression unchanged. But whatever changes happen because Messiah has come must arise from fulfillment, not contradiction.
A seed becoming a tree is change. It is not the destruction of the seed’s purpose. A promise being realized changes the situation. It does not make the promise false. A shadow meeting its substance changes how the shadow functions. It does not mean the shadow was evil.
Fulfillment is transformation through realization.
Abolition is dismantling.
Yeshua chose one and rejected the other.
But What About Sacrifices?
This is the question somebody should ask right now.
If not one jot or tittle passes from Torah, are we supposed to build an altar and start offering animals?
No.
And this is exactly why “Torah continues” cannot mean “Sinai continues unchanged.”
We have already studied the New Covenant. Hebrews gives us a changed priesthood, changed sacrifice, changed sanctuary, and changed mediation. Yeshua’s once-for-all sacrifice fulfills the sacrificial system by accomplishing what those sacrifices anticipated and could never finally accomplish on their own.
The sacrificial commands were not bad. They were not mistakes. Yehovah did not wake up one morning and decide the whole thing had been a poor idea.
Their purpose reaches its Messiah-centered reality.
This is precisely the sort of distinction we need when we talk about fulfillment. The question for every Torah instruction is not merely, “Does the sentence still exist?” Nor is it, “Did Yeshua fulfill it, therefore I ignore it?”
The better question is:
How does this instruction reach its intended function under the New Covenant Yeshua mediates?
Sometimes continuity is direct. Do not murder. Do not commit adultery. Honor Yehovah. Love your neighbor.
Sometimes the covenantal form changes profoundly: sacrifice, priesthood, sanctuary, national judicial administration.
Fulfillment makes us do more careful Bible study, not less.
Jeremiah Helps Us Here
Turn to Jeremiah 31:31–34. The promised New Covenant is not described as Yehovah removing His instruction from the lives of His people. He says He will place His Torah or instruction within them and write it on their hearts.
At the same time, Jeremiah explicitly says this covenant will be not like the covenant made when Israel came out of Egypt.
There is continuity.
And discontinuity.
Torah within.
Different covenant.
That is exactly the kind of tension Matthew 5 requires us to learn how to hold. Yeshua fulfills without abolishing. New without lawless. Changed without disconnected.
Messiah does not rescue us from the God who spoke at Sinai.
He brings Yehovah’s redemptive story to its appointed fullness.
What About “The Law and the Prophets Were Until John”?
Now read Matthew 11:13. Yeshua says, “All the Prophets and the Law prophesied until John.”
Some readers see the word until and conclude, “There. Torah ended when John appeared.”
But look at what Yeshua actually says the Law and Prophets were doing.
They prophesied until John.
The statement concerns the prophetic movement of Scripture toward the arriving kingdom and Messiah. John stands at a turning point. The forerunner has arrived. The Kingdom is breaking in.
The sentence does not say, “All divine instruction became invalid when John started preaching.”
Transition does not automatically mean abolition.
Heaven and Earth Show Up Again
Now turn to Matthew 24:35. Yeshua says heaven and earth will pass away, but His words will not pass away.
That is a remarkable statement beside Matthew 5:18.
In Matthew 5, heaven and earth provide the horizon for Torah’s endurance. Later, Yeshua says His own words outlast heaven and earth.
Whatever else we conclude, Matthew is not presenting Yeshua as merely one more rabbi offering an opinion beneath a higher authority.
He speaks with divine-level authority.
That has to be part of what fulfillment means.
The Law and Prophets arrive at their goal in a Person who has authority to tell us what their fullness looks like.
At the End of Matthew, Yeshua Still Commands Obedience
Now go all the way to the end.
Matthew 28:18–20.
Yeshua has risen.
This is after the cross.
After the resurrection.
He sends His disciples to the nations.
And what are they to teach?
Not, “Teach them that obedience was fulfilled so it no longer matters.”
They are to teach the nations to obey everything Yeshua commanded.
That does not mean Gentile disciples simply enter the Sinai covenant unchanged. Acts, Paul, and Hebrews would make that too simple.
But it tells us something important about discipleship after the resurrection.
Grace did not produce commandlessness.
Messiah did not fulfill righteousness so His disciples could stop caring about righteousness.
So What Exactly Did Yeshua Fulfill?
Now we have enough Scripture on the table to answer more carefully.
I think Yeshua fulfills the Law and Prophets in several overlapping ways. He fulfills them by faithfully embodying Yehovah’s righteousness. He does not teach rebellion against His Father and then call it fulfillment. His life is obedient, and that matters.
He also fulfills their prophetic hope. Matthew repeatedly presents Yeshua’s life as Scripture coming to realization. Messiah. Son of David. Son of Abraham. King. Kingdom. Israel’s story moving toward Him.
He fulfills their patterns. Priesthood, sacrifice, temple, exodus, Passover, sonship, and Israel’s calling all find climactic meaning in Him. These patterns do not become meaningless when Messiah comes. They reach the reality toward which they pointed.
He fulfills Torah by revealing its full righteous intention. Do not merely avoid murder; deal with hatred. Do not merely avoid physical adultery; deal with lust. Do not hide deception behind oath formulas. Do not use justice as an excuse for personal vengeance. Love even enemies. Yeshua carries righteousness into the heart.
He also fulfills by recovering creation purpose where Torah regulated human brokenness. Divorce is the clearest example. Moses permitted something because of hardness of heart, and Yeshua reaches backward to the beginning.
Finally, He fulfills by carrying the covenant story into its New Covenant stage. Messiah comes. Sacrifice reaches its goal. Priesthood changes. The Spirit is given. Torah is written upon hearts. Gentiles are brought near. The story moves forward.
Not because Moses failed.
Because Moses was never the final chapter.
What Fulfill Does Not Mean
Based on everything we have read, I do not think fulfill can responsibly be reduced to, “Yeshua obeyed Torah, therefore nothing changed.” That is too small.
I also do not think it can mean, “Yeshua completed Torah, therefore Torah became irrelevant.” That fights too hard against Matthew 5:18–20.
It cannot mean Yeshua replaced His Father’s instruction with a completely unrelated morality. His own teaching repeatedly grows out of Torah.
And it cannot mean every Sinai command continues in exactly the same covenantal form forever. The New Covenant, priesthood, sacrifice, sanctuary, and other genuine changes will not allow that.
We need a definition big enough for the whole Bible.
A Better Working Definition
Here is the definition I think best fits the evidence:
Yeshua fulfills the Law and the Prophets by faithfully embodying them, bringing their promises and patterns to realization, revealing their full righteous intention, and carrying Yehovah’s covenant story to its Messiah-centered New Covenant goal.
Read that slowly.
Faithfully embodying.
Bringing to realization.
Revealing fullness.
Carrying the story to its intended goal.
That definition allows real continuity and real change. It allows Yeshua to say, “I did not come to abolish,” while allowing Hebrews to say the priesthood changed. It allows Yeshua to affirm commandments while also reaching behind Moses’ divorce concession to Genesis. It allows Torah to remain Yehovah’s revelation without pretending covenant administration froze at Sinai.
That, to me, makes far more sense of the evidence.

Test the Claims We Hear
“Fulfill means abolish.”
Does Yeshua use two different words? What does He explicitly deny?
________________________________________________________________________________
“Fulfill simply means obey perfectly.”
Does “Law and Prophets” make the claim broader than command-keeping alone?
________________________________________________________________________________
“Verse 18 says the Law lasted only until Jesus fulfilled it.”
Does verse 18 use plēroō?
________________________________________________________________________________
“The Law disappeared at the cross.”
How do “heaven and earth,” verse 19, and the least commandments affect that claim?
________________________________________________________________________________
“Jesus only corrected Pharisaic traditions.”
Do the six examples engage Mosaic Torah itself? Which examples make the “tradition only” explanation difficult?
________________________________________________________________________________
“Jesus changed Torah, therefore He abolished it.”
Can fulfillment include authoritative transformation without treating earlier revelation as false or evil?
________________________________________________________________________________
“Jesus said love replaced the commandments.”
Where do His two love commandments come from?
________________________________________________________________________________
“If Yeshua did not abolish Torah, every Sinai command must operate identically today.”
How do priesthood, sacrifice, sanctuary, divorce, and covenant administration challenge that claim?
________________________________________________________________________________
“The Sermon on the Mount is less demanding than Torah because Christians are under grace.”
Read Matthew 5:20–48 again. Does that survive?
________________________________________________________________________________
Now Test the Torah-Observant Shortcut
We need to test ourselves too.
“Fulfill means Yeshua merely showed us how to obey Moses.”
Is “merely” big enough for Matthew’s Messiah?
________________________________________________________________________________
“Every ‘but I say to you’ only corrects Pharisaic oral tradition.”
Does that fully explain divorce, oaths, or “eye for eye”?
________________________________________________________________________________
“Matthew 5:18 means covenant administration can never change.”
How would that fit Hebrews?
________________________________________________________________________________
“Least commandments means every command has equal weight.”
What does Matthew 23:23 say about weightier matters?
________________________________________________________________________________
“Yeshua’s teaching is just Moses repeated.”
Why does He speak with the authority, “But I say to you”?
________________________________________________________________________________
We do not honor Torah by shrinking Yeshua.
And we do not honor Yeshua by making Torah His enemy.
☕ Coffee Break With Sasha
Okay. Coffee.
Because this is the point where I want to tell you what drives me a little crazy about this verse.
We quote, “I did not come to abolish but to fulfill,” and then sometimes we explain it as though Yeshua said, “I did not come to abolish. I came to abolish in a different way.”
And I am sitting here with my coffee going, “Do words still mean things?”
If I tell my girls, “I did not come into your room to throw away your clothes. I came to complete your clothes,” and then I take every shirt to Goodwill, I am going to have some explaining to do.
That is not a perfect analogy. Please do not build a denomination around my daughters’ closet. But you see the problem.
If fulfill means functionally the exact same thing as abolish, why does Yeshua contrast them?
Then He immediately says heaven and earth, jot and tittle, least commandment, do and teach, exceeding righteousness.
That is a very strange way to announce, “Good news, everybody. None of this matters now.”
It just is.
But my Torah-observant friends can make the opposite mistake. We can read, “I did not abolish,” and decide Yeshua basically came to say, “Carry on exactly as before. Nothing to see here.”
Um.
Have you met Yeshua?
Because about five minutes later He is saying, “You have heard... but I say to you.”
Everybody on that mountain should probably sit up a little straighter.
He is not merely reading a study Bible note. He is speaking with authority.
Moses says divorce was permitted. Yeshua says, “Let Me take you back before Moses. Genesis. Beginning. Creation.”
That gets my attention.
Then we get to “eye for eye.” Torah was not saying, “If somebody bumps you at Walmart, knock their tooth out.” It was proportional judicial justice. But Yeshua tells His disciples something even more radical: do not run your personal relationships on retaliation.
Then enemies.
Love them.
Pray for them.
Why?
Because that is what your Father is like.
Are you picking up what I’m throwing down?
Yeshua is not making Torah smaller.
He is making righteousness impossible to fake.
That is what gets me.
We like measurable religion.
Did I murder anybody today? Nope. Check.
Adultery? Nope. Check.
And Yeshua says, “How is your anger?”
Excuse me?
“What are you doing in your mind?”
Sir, I preferred the checklist.
“Are you reconciled with your brother?”
Can we go back to murder?
“Do you tell the truth so consistently that you do not need verbal tricks to convince people you mean it?”
This study is getting personal.
“Do you retaliate?”
“Do you love enemies?”
I suddenly have some errands to run.
That is fulfillment as I see it. Not “throw Moses away,” and not “freeze Moses in place and never move forward.” It is Yeshua taking Yehovah’s revelation and saying, “Let Me show you where this has been going.”
And the answer is not less righteousness.
It is deeper righteousness.
Heart righteousness.
Kingdom righteousness.
Messiah-shaped righteousness.
Then after all that, He dies, rises, becomes our High Priest, offers the once-for-all sacrifice, mediates the New Covenant, sends the Spirit, and now we have to figure out how Torah functions on this side of all of that.
That takes work.
I know.
Terribly inconvenient.
It would be so much easier if fulfill meant “delete.”
Or if it meant “nothing changed.”
One word. One slogan. Close Bible. Finish coffee.
But Scripture refuses to cooperate.
So here is where I land: Yeshua did not come to rescue us from Yehovah’s instruction. He came to bring Yehovah’s entire redemptive revelation to its intended fullness.
And once the One everything was moving toward finally arrives, things do change.
But they change because the story reached Messiah.
Not because Yehovah’s earlier Word was wrong.
That difference is huge.

What I Think the Evidence Shows
Here is where I land.
I do not believe fulfill means abolish. Yeshua explicitly tells us it does not.
I also do not believe fulfill simply means, “Yeshua personally obeyed Torah so nothing changed.” That is too small for Matthew’s Gospel and too small for the New Covenant.
I think fulfill means Yeshua brings Yehovah’s Law and Prophets to their intended fullness and realization. He obeys them, embodies them, reveals their deepest righteousness, fulfills their promises, completes their patterns, recovers their creation purpose, and carries the covenant story into its Messiah-centered New Covenant reality.
That is not abolition.
And it is not stagnation.
It is fulfillment.
Yeshua Did Not Come to Make Righteousness Irrelevant
Matthew 5 does not sound remotely like, “Good news. Righteousness no longer matters.”
Yeshua tells His disciples their righteousness must exceed that of respected religious teachers, then spends the chapter showing what that means.
Anger matters.
Lust matters.
Marriage matters.
Truth matters.
Retaliation matters.
Enemy-love matters.
The heart matters.
If this is Yeshua abolishing obedience, He has a fascinating way of showing it.
The movement of the sermon is toward greater integrity.
Not less.
Yeshua Is More Than a Torah Commentator
But He is also more than another teacher standing beneath Torah explaining a difficult paragraph. He speaks with His own authority.
“But I say to you.”
He has authority to identify what Moses permitted because of hardness of heart. He reaches behind covenant concession to creation. He defines kingdom righteousness. After His resurrection, He commands the nations to obey everything He taught.
The Messiah is the authoritative interpreter because the Scriptures reach their goal in Him.
We should not flatten that authority in an attempt to defend Torah.
Torah itself was pointing toward Him.
New Covenant Change Does Not Equal Torah Failure
The fact that the priesthood changes does not mean Yehovah made a mistake with Levi. The fact that Yeshua’s sacrifice is once for all does not mean animal sacrifices were pointless. The fact that the sanctuary reality changes does not make the tabernacle false.
Those institutions were telling the truth.
They were telling it ahead of time.
Messiah brings the truth they carried into its fuller reality.
That is fulfillment.
And I think that category helps us understand many difficult Torah questions without choosing between two extremes:
“Everything ended.”
Or:
“Nothing changed.”
Love Does Not Replace Torah
Yeshua’s greatest commandments come from Torah.
Love Yehovah: Deuteronomy.
Love neighbor: Leviticus.
Then Yeshua says the Law and Prophets hang on them.
Love is not the opposite of commandment.
It is the heart that makes commandments coherent.
Biblical love is not simply, “Do whatever feels kind.”
Yehovah teaches His people what love looks like.
That is why Yeshua can summarize without erasing.
Fulfillment Makes Torah More Personal, Not Less
One of the biggest things I see in the Sermon on the Mount is that Yeshua will not let me hide behind technical compliance.
I can refrain from murder and hate someone.
Yeshua sees it.
I can refrain from physical adultery while using another person sexually in my imagination.
Yeshua sees it.
I can create sophisticated language to make some promises binding and others conveniently flexible.
Yeshua sees it.
I can demand justice when what I really want is revenge.
Yeshua sees it.
I can love people who love me and call myself righteous.
Yeshua asks about my enemies.
That is what fulfilled righteousness feels like.
It gets into places a checklist cannot reach.
A Safer “Fulfill” Checklist
When someone tells you what Matthew 5:17 means, begin by asking whether the definition preserves Yeshua’s explicit denial of abolition. If fulfill means functionally the same thing as abolish, something has gone wrong.
Then read verses 18–20. Never build the doctrine from verse 17 alone. Notice that verse 18 does not repeat plēroō. Account for the language of heaven and earth, the warning about loosening commandments, and Yeshua’s demand for greater righteousness.
Let Matthew’s earlier uses of fulfillment help define Matthew’s language. Remember that Yeshua says Law and Prophets, not simply “rules.” Allow the “You have heard... but I say” passages to be genuinely difficult. Do not pretend every example is merely a correction of later tradition, and do not pretend every example is simply Yeshua discarding Moses.
Remember the New Covenant. Sinai’s administration does not continue untouched.
Remember love. Yeshua’s summary comes from Torah itself.
And remember Yeshua.
Do not defend Torah by making Messiah smaller.
One More Question
Imagine you had never heard the phrase, “Jesus fulfilled the Law so we don’t have to.”
And imagine you had never heard, “Fulfill only means obey perfectly.”
You simply opened Matthew.
Matthew keeps telling you Scriptures are being fulfilled in Yeshua—not discarded, but brought to realization.
Then Yeshua tells John, “We must fulfill all righteousness.”
Then He climbs a mountain and tells His disciples, “Do not think I came to abolish the Law or Prophets. I did not. I came to fulfill.”
Then He talks about heaven and earth, tiny letters, least commandments, doing and teaching, and righteousness exceeding the scribes and Pharisees.
Then He says:
You have heard.
But I say.
Do not merely avoid murder.
Confront hatred.
Do not merely avoid adultery.
Confront lust.
Do not hide behind divorce concessions.
Go back to creation.
Be radically truthful.
Do not retaliate.
Love enemies.
Be like your Father.
Near the end of the sermon He says, “This is the Law and the Prophets.”
Later He says, “Love Yehovah. Love neighbor. On these hang the Law and Prophets.”
Later still He speaks of justice, mercy, and faithfulness as weightier matters of Torah.
Then after His resurrection He tells His disciples to teach the nations to obey everything He commanded.
If you encountered all of that without a theology book telling you beforehand what fulfill had to mean, would your natural conclusion be:
“Yeshua made Yehovah’s instruction irrelevant”?
I do not think mine would.
But neither would I conclude:
“Messiah came and nothing changed.”
Something far bigger is happening.
The Scriptures are reaching their King.
Final Thought
I think we have made the word fulfill carry a fight it was never meant to carry.
One side hears “fulfilled” and thinks, “Finished. Gone. No longer relevant.” The other hears “not abolished” and thinks, “Nothing changed.”
Yeshua gives us something better.
The Torah and Prophets were going somewhere. Toward righteousness. Toward restoration. Toward covenant faithfulness. Toward the Kingdom. Toward Messiah.
And when Messiah arrives, He does not set fire to the road behind Him.
He shows us where the road was leading.
He embodies it, completes its promises, fills its patterns, corrects our distortions, takes righteousness into the heart, moves beyond concessions created by hardness, brings sacrifice to its once-for-all reality, and carries covenant into its promised newness.
Then He turns to His disciples and says:
Follow Me.
That is why I cannot make fulfill mean abolish.
Yeshua already told me not to.
But I also cannot make fulfill mean nothing changes.
Yeshua Himself is the change everything was moving toward.
So when I read:
“I did not come to abolish but to fulfill,”
this is what I hear:
I did not come to tear down My Father’s revelation.
I came to bring it where it was always going.
And if I want to understand what that looks like now, I do not get to stop at Moses.
I follow Moses to Messiah.
Then I listen to Messiah.
Don't take my word for it.
Open your Bible.

Study Notes
Kataluō — “Abolish”
Matthew 5:17 uses καταλύω — kataluō, a verb capable of describing demolition, destruction, dissolution, or overthrow. In this context, it describes abolishing or dismantling the Law and Prophets. Yeshua explicitly denies that this is His mission.
Plēroō — “Fulfill”
πληρόω — plēroō has a range including filling, completing, bringing into effect, and bringing something into realization. Matthew repeatedly uses the word for Scripture finding realization in events surrounding Yeshua, and Matthew 3:15 uses the same verb in Yeshua’s statement about “fulfilling all righteousness.” The lexical range alone does not settle Matthew 5:17; the surrounding context must determine how the word functions.
The Law and the Prophets
“The Law and the Prophets” functions in Matthew as a broad designation for Israel’s scriptural revelation. Matthew 7:12 and Matthew 22:40 use the same pairing when Yeshua describes the ethical center of Scripture. This makes Matthew 5:17 broader than a statement concerning isolated legal commands.
Matthew’s Fulfillment Theme
Matthew characteristically presents Yeshua as bringing Israel’s Scriptures and story into realization. Fulfillment in Matthew is often richer than a narrow prediction-and-event formula; Yeshua’s life gathers up and gives climactic realization to Israel’s scriptural story.
Matthew 5:18 — “Until All Comes to Pass”
The Greek of verse 18 does not repeat plēroō. It uses a form of ginomai in the phrase heōs an panta genētai—until all happens or comes to pass. English translations using “fulfilled” in verse 18 can obscure the lexical distinction between verses 17 and 18.
Iota and Keraia
Yeshua’s imagery in Matthew 5:18 points to extremely small written details. The iota is the smallest Greek letter and evokes the tiny Hebrew yod, while keraia refers to a small stroke or projection of a letter. The saying emphasizes the seriousness with which Yeshua treats Scripture.
Kataluō and Lyō
There is a verbal connection between Matthew 5:17 and 5:19 that English can hide. Yeshua says He did not come to kataluō the Law and Prophets; verse 19 warns against whoever lyō—loosens, sets aside, or breaks—even a least commandment. Kataluō is built from the same basic luō root, strengthening the literary connection between Yeshua’s denial of abolition and His warning against loosening commandments.
“These Commandments”
Interpreters disagree over whether Matthew 5:19’s “these commandments” refers most immediately to Torah commandments just discussed or to Yeshua’s kingdom commands in the sermon that follows. The immediate context strongly connects the statement with Torah, while Matthew also presents Yeshua as Torah’s authoritative interpreter for His disciples.
“Until Heaven and Earth Pass”
Matthew 5:18 has produced substantial debate. Some interpreters place “until all comes to pass” primarily at the fulfillment achieved through Messiah; others emphasize the parallel “until heaven and earth pass” and understand the horizon as extending to the final consummation. A simplistic claim that verse 18 clearly makes Torah expire during Yeshua’s earthly ministry does not account well for the full wording.
The Antitheses
Matthew 5:21–48 is often called the “Antitheses” because of the repeated “You have heard... but I say” structure. Interpreters disagree over whether Yeshua primarily corrects contemporary interpretation, intensifies Torah, or in some cases authoritatively redirects Mosaic provisions. Several of the opening statements directly quote or closely reflect Torah itself, making it difficult to explain the entire section solely as a dispute with later Pharisaic tradition.
Greater Righteousness
Matthew 5:20 introduces the examples that follow. Yeshua’s kingdom ethic does not lower Torah’s standards; the sermon repeatedly presses righteousness into motive, desire, integrity, mercy, reconciliation, and love. Whatever precise relationship one sees between Yeshua’s teaching and Mosaic law, Matthew presents discipleship as demanding rather than morally relaxed.
Weightier and Lighter Matters
Matthew 23:23 shows Yeshua distinguishing “weightier matters” of the Law—justice, mercy, and faithfulness—without declaring every lesser matter meaningless. The idea that commands may differ in weight provides useful background for Matthew 5:19’s language about “least” commandments.
Continuity and Fulfillment
A careful reading of Matthew must preserve both continuity and transformation. Yeshua explicitly denies abolishing Israel’s Scriptures, affirms their enduring significance, and warns against loosening commandments. At the same time, Matthew presents Yeshua as the Messiah whose authority, teaching, death, resurrection, and New Covenant work bring those Scriptures to their intended goal. Fulfillment therefore cannot be reduced either to abolition or to an unchanged continuation of Sinai.
