Exodus 12:15 tells Israel to eat unleavened bread for seven days and to clear every trace of yeast from their homes before the feast begins. Anyone who eats leavened bread during that week is cut off from the community. God gives this instruction through Moses and Aaron as part of the first Passover, so it is spoken to the people of Israel who are about to leave Egypt.
“‘Seven days you shall eat unleavened bread; even the first day you shall put away yeast out of your houses, for whoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.

What Exodus 12:15 Means
The phrase “seven days you shall eat unleavened bread” sets the length and the menu of the festival. Bread made without yeast is flat and dense, the kind of bread a household could bake quickly. The people are being told to shape their whole week around a simple food that recalls their hurried departure from Egypt.
The instruction to “put away yeast out of your houses” goes further than the meal itself. Yeast was a common ingredient, so removing it meant a deliberate search of the home and a clean break with ordinary routine. The verse asks for a visible, practical separation before God’s appointed days begin.
The warning that anyone who eats leavened bread “shall be cut off from Israel” is severe, and the text does not soften it. It describes exclusion from the covenant community, not a minor fine. The verse promises nothing about personal comfort or outcomes. It names God’s expectation and the seriousness of setting it aside.
The Context of Exodus 12:15
Exodus is traditionally attributed to Moses and tells the story of Israel’s deliverance from slavery in Egypt and the giving of the law at Sinai. Verse 15 sits inside the Passover narrative, where God announces the final plague against Egypt and the sign of the lamb’s blood on the doorposts. The Israelites reading this account would have been the very people who lived through the night of their rescue.
The verses just before and after show why the feast matters. Verses 12 and 13 describe God passing through Egypt and sparing the houses marked with blood, and verses 14 and 17 call the day a memorial to be kept forever. Verse 15 is the practical rule that turns that memory into a repeated, lived habit, so the reader sees the bread as part of remembering a rescue.

A Short Prayer From Exodus 12:15
Lord, you gave your people a way to remember your rescue, and you asked them to make that memory part of their daily bread. Search my heart and my home the way Israel searched their houses for yeast. Show me what has crept in quietly and needs to be removed, and give me the courage to clear it out. Keep me faithful to the things you have asked me to remember, and let each ordinary meal remind me of your steady deliverance. Amen.
