Exodus 12:7-13

7They are to take some of the blood and smear it on the sides and top of the doorframes of the houses where they eat the animal.

8That same night they must roast the meat over a fire and eat it along with bitter salad greens and bread made without yeast.

9Do not eat any of the meat raw or boiled in water. The whole animal—including the head, legs, and internal organs—must be roasted over a fire.

10Do not leave any of it until the next morning. Burn whatever is not eaten before morning.

11“These are your instructions for eating this meal: Be fully dressed, wear your sandals, and carry your walking stick in your hand. Eat the meal with urgency, for this is the Lord’s Passover.

12On that night I will pass through the land of Egypt and strike down every firstborn son and firstborn male animal in the land of Egypt. I will execute judgment against all the gods of Egypt, for I am the Lord!

13But the blood on your doorposts will serve as a sign, marking the houses where you are staying. When I see the blood, I will pass over you. This plague of death will not touch you when I strike the land of Egypt.
