13 The blood on the doorposts will be a sign to mark the houses in which you live. When I see the blood, I will pass over you and will not harm you when I punish the Egyptians.
14 You must celebrate this day as a religious festival to remind you of what I, the Lord, have done. Celebrate it for all time to come.”
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.”
