Exodus 12:18-20 ▼

18 In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread until the twenty-first day of the month at evening.

19 Seven days there shall be no leaven found in your houses; for whoever eats what is leavened, that person shall be cut off from the congregation of Israel, whether he is a sojourner or a native of the land.

20 You shall not eat anything leavened; in all your places of habitation you shall eat unleavened bread.’”
