Seven days of flat bread that remembered a night Israel left Egypt in a hurry, and why Paul told a mostly Gentile church to keep the feast without ever mentioning a loaf.
The Feast of Unleavened Bread is the seven-day festival that follows Passover, from the fifteenth to the twenty-first of the month of Nisan, when Israel removed every trace of leaven from the house and ate matzah. It remembers a people who left Egypt too quickly for their dough to rise.
For Christians it is fulfilled rather than required. Christ our Passover has been sacrificed, and Paul tells the church to keep the feast with the unleavened bread of sincerity and truth, which is a way of living, not a date on a calendar.
The rest of this post walks through where the feast comes from, how Jewish families keep it today, what leaven means in Scripture, and where we stand on observing it.
The instructions sit in three places. Exodus 12:15 to 20 gives them on the night of the exodus itself. Exodus 13:3 to 10 repeats them as something parents explain to their children. Leviticus 23:6 to 8 sets them into Israel's yearly calendar alongside the other appointed feasts.
The rules are simple. For seven days, eat bread made without yeast. On the first day, remove the yeast from your houses. The first and the seventh day are sacred assemblies with no ordinary work. Anyone who ate leaven that week was to be cut off from Israel.
“With the dough the Israelites had brought from Egypt, they baked loaves of unleavened bread. The dough was without yeast because they had been driven out of Egypt and did not have time to prepare food for themselves.”
Exodus 12:39That verse is the reason for the whole week. The bread did not rise because there was no time to let it. Deuteronomy 16:3 calls matzah the bread of affliction and ties it directly to the fact that Israel left Egypt “in haste.” Every flat loaf said the same thing: you did not walk out of slavery on your own schedule. God brought you out, and He did it fast.
The lamb is slaughtered at twilight and eaten that night with bitter herbs and bread made without yeast (Exodus 12:6 to 8).
The Feast of Unleavened Bread begins (Leviticus 23:6). No regular work, and the leaven is already gone from the house.
Work goes on, but every meal is eaten without leaven. The memory is kept at the kitchen table, not only in worship.
The week closes the way it opened, with a holy gathering (Exodus 12:16, Leviticus 23:8).
The feast was built so a child would ask why the bread is different, and a parent would answer, “I do this because of what the LORD did for me when I came out of Egypt” (Exodus 13:8).
Technically, Passover is the meal on the evening of the fourteenth and the Feast of Unleavened Bread is the week that follows. In practice the two were folded together long before Jesus was born, and by the first century people used either name for the whole festival.
“Now the Festival of Unleavened Bread, called the Passover, was approaching”
Luke 22:1Luke sees no tension there, and neither did anyone in Jerusalem. Mark 14:12 even calls the day the lambs were sacrificed “the first day of the Festival of Unleavened Bread.” Jewish practice today does the same thing, and the whole holiday is simply called Pesach.
Unleavened bread. Dough baked before it has a chance to ferment and rise.
Chag HaMatzot, the Festival of Unleavened Bread, in Leviticus 23:6.
Chametz, leavened food. This is what gets searched out and removed from the house.
The bread of affliction, in Deuteronomy 16:3. Poor bread, fast bread, slave bread turned into freedom bread.
This matters for reading the Gospels. When the Last Supper happens, Jesus is sitting inside this week of memory, holding the bread of affliction when He says, “This is my body.” We walk through that meal in the significance of the Last Supper, and the lamb and the night itself have their own post on what Passover is in the Bible.

Manage My Giving"Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver."2 Corinthians 9:7
This part deserves care, because the feast still belongs to living people who keep it with real devotion. What follows is description, not critique, and practice varies from one community to the next.
In the weeks before Pesach, households clear out leavened food: bread, cereal, anything made from grain that has been allowed to ferment. Many families switch to separate dishes for the week.
On the night before, the house is searched for leaven. Some families hide ten pieces so the children have something to find, and the crumbs are swept up with a feather into a spoon and a bag.
Afterward a declaration is said, which Reform Judaism's guide renders as “Any leaven that is in my possession, that I have not seen or not removed, shall be unclaimed and considered as the dust of the earth.” The next morning the bag is burned or thrown out.
Matzah is made from flour and water only, worked and baked quickly so it cannot rise. The festival runs seven days in Israel and, in many communities, eight days elsewhere.
Notice the honesty in that declaration. You search as carefully as you can, then admit you probably missed something and let it go.
You may have heard that matzah proves Jesus is the Messiah because it is striped and pierced, echoing Isaiah 53:5. It is a moving image, and it is on our side, and it still does not hold up the way it is usually told.
The stripes and holes in matzah were put there to point to the wounds of the Messiah, so every Passover table is secretly preaching Jesus.
The holes keep the dough from puffing up in the oven. The flat square cracker most of us picture owes a lot to the matzah machine invented in 1838. Nobody designed matzah as a prophecy.
You do not need the folklore to see Jesus in the bread. He told us Himself what it means.
A lot of teaching on this feast says leaven always means sin in the Bible. That is too flat. Leaven is an image of influence, and Scripture uses it in both directions. What it pictures depends on who is speaking and what they are pointing at.
1 Corinthians 5:6 asks, “Don't you know that a little yeast leavens the whole batch of dough?” He is writing to a church that tolerated something destructive and was proud of it. A little of that spreads everywhere.
In Matthew 16:6 Jesus warns, “Be on your guard against the yeast of the Pharisees and Sadducees.” Verse 12 explains He meant their teaching. Bad ideas work quietly through a whole community. More on the people He meant in who were the Pharisees.
Then in Matthew 13:33 the same image means the opposite: “The kingdom of heaven is like yeast that a woman took and mixed into about sixty pounds of flour until it worked all through the dough.”
That last parable sits right next to the parable of the mustard seed, and the two make the same point from different angles. Something small and hidden goes in and changes everything around it. The Kingdom is not waiting to arrive. It is already in the dough, already working, and it keeps working until the whole batch is reached. We say more about that in what the Kingdom of God is.
“Therefore let us keep the Festival, not with the old bread leavened with malice and wickedness, but with the unleavened bread of sincerity and truth.”
1 Corinthians 5:8Malice spreads through a people, false teaching spreads, and so does the Kingdom. The question is never whether something is working through you. The question is what.
Look at what Paul does in 1 Corinthians 5. He is writing to a mostly Gentile church in Corinth, and he says, “Christ, our Passover lamb, has been sacrificed.” Then he says, “let us keep the Festival.” But he never gives a date, a week, or a baking instruction. The festival he means is a life, and sincerity and truth are the bread.
The feast was a shadow, and Jesus is the one who cast it.
“Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. These are a shadow of the things that were to come; the reality, however, is found in Christ.”
Colossians 2:16 to 17At Sound of Heaven we believe the Feast of Unleavened Bread was a good gift from God to Israel, that it is fulfilled in Jesus, and that no Christian is required to keep it. It is the same position we lay out in Old Testament laws. The old covenant order reached its end in the first century, and the reality it pointed to is Christ Himself, as we explain in how Jesus fulfilled the law.
There are two errors here, and we refuse both. The first says believers must keep the biblical feasts to be faithful, obedient, or fully blessed. That is the heart of much Hebrew Roots teaching, and it is wrong. It lands hardest on sincere new believers who are told their faith is incomplete until they add a calendar. Paul wrote the whole letter to the Galatians against that pressure.
The second error is contempt. Some Christians treat Jewish observance as empty ritual or something to mock. That is also wrong. A Jewish family searching their home for crumbs is remembering the God of Abraham with care, and they deserve respect.
In between is freedom. If a Christian family wants to host a Passover-style meal to teach their kids the exodus story, that is fine, and Romans 14 leaves room for it. It just can never become a test of anyone's faith.
Why did Paul tell the Corinthians to “keep the Festival”?
Paul never gives a date or a recipe. He takes the language of the feast and applies it to the life of a church that belongs to Christ. The shadow has already met its reality.
The Israelites ate flat bread because God moved faster than their dough. They did not earn the exodus and they did not plan it. They were carried out.
That is still how freedom works. Jesus did not wait for us to get the house clean before He came for us. He is the Lamb, and He is also the bread. “I am the bread of life,” He said in John 6:35, and we unpack that in the bread of life. The Feast of Unleavened Bread was one week of remembering. In Christ it has become a whole life of living free.
So the question this feast leaves with you is not whether you ate matzah this spring. It is what is working through you right now, malice or sincerity and truth. If there is old leaven you keep finding in the corners, you do not have to sweep it out alone. Ask us to pray with you.
For related reading, see what unleavened bread is, the Lord's Supper, the Feast of Booths and what day the Sabbath is.
Seven days of bread that had no time to rise, kept by Israel to remember a hurried rescue, fulfilled in Christ our Passover, and kept by us now as a life of sincerity and truth rather than a date anyone is required to observe.
If something keeps spreading in your life and you are tired of fighting it alone, send it to us, and someone at Sound of Heaven will pray with you by name.
The Feast of Unleavened Bread is a seven-day festival commanded in Exodus 12 and Leviticus 23, running from the fifteenth to the twenty-first of Nisan, right after Passover. Israel removed all leaven from their homes and ate matzah to remember that they left Egypt so quickly their dough had no time to rise. The first and seventh days were sacred assemblies. Jewish families still keep it today as part of Pesach, and for Christians its meaning is fulfilled in Jesus, Christ our Passover.
It begins on the fifteenth day of Nisan, the first month of the biblical calendar, and runs through the twenty-first. Passover falls on the fourteenth, so the two sit back to back. Because the Jewish calendar follows the moon, the dates move on the Western calendar and usually land in March or April. Today the festival lasts seven days in Israel and, in many communities outside Israel, eight days, and the whole holiday is commonly called Pesach.
Strictly, Passover is the lamb and the meal on the evening of the fourteenth of Nisan, and the Feast of Unleavened Bread is the seven days that follow, from the fifteenth to the twenty-first. In practice the two were combined long ago. Luke 22:1 speaks of the Festival of Unleavened Bread, called the Passover, and Mark 14:12 calls the day the lambs were sacrificed the first day of Unleavened Bread. Today the whole observance is simply called Passover or Pesach.
No. Colossians 2:16 to 17 says festivals were a shadow of the things to come and the reality is found in Christ. Paul tells the Corinthians to keep the feast with the unleavened bread of sincerity and truth, which is a way of life, not a calendar date. Teaching that believers must keep the feasts to be faithful is an error. Mocking Jewish observance is an error too. A Christian family may share a Passover-style meal freely, without making it a test of faith.
Leaven is an image of influence, and Scripture uses it in both directions. Paul uses it for malice and wickedness spreading through a church in 1 Corinthians 5, and Jesus uses it for the teaching of the Pharisees and Sadducees in Matthew 16. But in Matthew 13:33 Jesus compares the Kingdom of heaven itself to yeast working through a large batch of dough. So leaven does not always mean sin. It pictures something small that spreads until it affects everything around it.
