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.
20. You shall not consume any leaven. In all your dwelling places, you shall eat unleavened bread."
21. Then Moses called all the elders of the sons of Israel, and he said to them: "Go, taking an animal by your families, and sacrifice the Passover.
22. And dip a little bundle of hyssop in the blood which is at the entrance, and sprinkle the upper threshold with it, and both of the door posts. Let none of you go out of the door of his house until morning.
23. For the Lord will cross through, striking the Egyptians. And when he will see the blood on the upper threshold, and on both the door posts, he will pass over the door of the house and not permit the Striker to enter into your houses or to do harm.
24. You shall keep this word as a law for you and for your sons, forever.
