Exodus 12:13

9Don’t eat it raw, nor boiled at all with water, but roasted with fire; with its head, its legs and its inner parts.

10You shall let nothing of it remain until the morning; but that which remains of it until the morning you shall burn with fire.

11This is how you shall eat it: with your belt on your waist, your sandals on your feet, and your staff in your hand; and you shall eat it in haste: it is the LORD’s Passover.

12For I will go through the land of Egypt in that night, and will strike all the firstborn in the land of Egypt, both man and animal. I will execute judgments against all the gods of Egypt. I am the LORD.

13The blood shall be to you for a token on the houses where you are. When I see the blood, I will pass over you, and no plague will be on you to destroy you when I strike the land of Egypt.

14This day shall be a memorial for you. You shall keep it as a feast to the LORD. You shall keep it as a feast throughout your generations by an ordinance forever.

15“‘Seven days you shall eat unleavened bread; even the first day you shall put away yeast out of your houses, for whoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.

16In the first day there shall be to you a holy convocation, and in the seventh day a holy convocation; no kind of work shall be done in them, except that which every man must eat, only that may be done by you.

17You shall observe the feast of unleavened bread; for in this same day I have brought your armies out of the land of Egypt. Therefore you shall observe this day throughout your generations by an ordinance forever.
