13 But the blood will be for you as a sign in the buildings where you will be. And I will see the blood, and I will pass over you. And the plague will not be with you to destroy, when I strike the land of Egypt.
14 Then you shall have this day as a memorial, and you shall celebrate it as a solemnity to the Lord, in your generations, as an everlasting devotion.
15 For seven days, you shall eat unleavened bread. On the first day there shall be no leaven in your houses. Whoever will consume anything leavened, from the first day, even until the seventh day, that soul shall perish from Israel.
16 The first day shall be holy and solemn, and the seventh day shall be venerated with the same festivity. You shall do no work in these days, except that which pertains to the eating.
17 And you shall observe the feast of unleavened bread. For on this same day, I will lead your army out of the land of Egypt, and you shall keep this day, in your generations, as a perpetual ritual.
18 In the first month, on the fourteenth day of the month, toward evening, you shall consume the unleavened bread, until the twenty-first day of the same month, toward evening.
19 For seven days, there shall not be found leaven in your houses. Whoever will eat leaven, his soul will perish from the assembly of Israel, as much with the newcomers as with the natives of the land.
