Exodus 12:10-14

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.

14“This is a day to remember. Each year, from generation to generation, you must celebrate it as a special festival to the Lord. This is a law for all time.
