¹⁷ You must remember the Festival of Unleavened Bread, because on this day I took all of your people out of Egypt in groups.^[a] All of your descendants must remember this day. This is a law that will last forever. ¹⁸ So on the evening of the 14th day of the first month, you will begin eating bread without yeast. You will eat this bread until the evening of the 21st day of the same month. ¹⁹ For seven days, there must not be any yeast in your houses. Anyone, either a citizen of Israel or a foreigner living among you,^[b] who eats yeast at this time must be separated from the rest of Israel.
