Exodus 12:7-13

7They must take some of the blood and put it on the two doorposts and the lintel of the houses where they eat them.

8They are to eat the meat that night; they should eat it, roasted over the fire along with unleavened bread and bitter herbs.

9Do not eat any of it raw or cooked in boiling water, but only roasted over fire — its head as well as its legs and inner organs.

10You must not leave any of it until morning; any part of it left until morning you must burn.

11Here is how you must eat it: You must be dressed for travel, your sandals on your feet, and your staff in your hand. You are to eat it in a hurry; it is the Lord’s Passover.

12“I will pass through the land of Egypt on that night and strike every firstborn male in the land of Egypt, both people and animals. I am the Lord; I will execute judgments against all the gods of Egypt.

13The blood on the houses where you are staying will be a distinguishing mark for you; when I see the blood, I will pass over you. No plague will be among you to destroy you when I strike the land of Egypt.
