Exodus 12:7-14

7Then they are to take some of the blood and put it on the sides and tops of the doorframes of the houses where they eat the lambs. 8That same night they are to eat the meat roasted over the fire, along with bitter herbs, and bread made without yeast. 9Do not eat the meat raw or boiled in water, but roast it over a fire—with the head, legs and internal organs. 10Do not leave any of it till morning; if some is left till morning, you must burn it.

11This is how you are to eat it: with your cloak tucked into your belt, your sandals on your feet and your staff in your hand. Eat it in haste; it is the LORD ’s Passover. 12“On that same night I will pass through Egypt and strike down every firstborn of both people and animals, and I will bring judgment on all the gods of Egypt. I am the LORD .

13The blood will be a sign for you on the houses where you are, and when I see the blood, I will pass over you. No destructive plague will touch you when I strike Egypt. 14“This is a day you are to commemorate; for the generations to come you shall celebrate it as a festival to the LORD —a lasting ordinance.
