Exodus 12:15–20

¹⁵For seven days the bread you eat must be made without yeast. On the first day of the festival, remove every trace of yeast from your homes. Anyone who eats bread made with yeast during the seven days of the festival will be cut off from the community of Israel. ¹⁶On the first day of the festival and again on the seventh day, all the people must observe an official day for holy assembly. No work of any kind may be done on these days except in the preparation of food.

¹⁷“Celebrate this Festival of Unleavened Bread, for it will remind you that I brought your forces out of the land of Egypt on this very day. This festival will be a permanent law for you; celebrate this day from generation to generation. ¹⁸The bread you eat must be made without yeast from the evening of the fourteenth day of the first month until the evening of the twenty-first day of that month. ¹⁹During those seven days, there must be no trace of yeast in your homes. Anyone who eats anything made with yeast during this week will be cut off from the community of Israel. These regulations apply both to the foreigners living among you and to the native-born Israelites. ²⁰During those days you must not eat anything made with yeast. Wherever you live, eat only bread made without yeast.”
