15 The Lord said, “For seven days you must not eat any bread made with yeast — eat only unleavened bread. On the first day you are to get rid of all the yeast in your houses, for if anyone during those seven days eats bread made with yeast, he shall no longer be considered one of my people.
16 On the first day and again on the seventh day you are to meet for worship. No work is to be done on those days, but you may prepare food.
17 Keep this festival, because it was on this day that I brought your tribes out of Egypt. For all time to come you must celebrate this day as a festival.
18 From the evening of the fourteenth day of the first month to the evening of the 21st day, you must not eat any bread made with yeast.
19-20 For seven days no yeast must be found in your houses, for if anyone, native-born or foreign, eats bread made with yeast, he shall no longer be considered one of my people.”
21 Moses called for all the leaders of Israel and said to them, “Each of you is to choose a lamb or a young goat and kill it, so that your families can celebrate Passover.
22 Take a sprig of hyssop, dip it in the bowl containing the animal's blood, and wipe the blood on the doorposts and the beam above the door of your house. Not one of you is to leave the house until morning.
