Exodus 12:7-13

7They must take some of its blood. They must put the blood on the wood that is round the door of their house. They must put it on each side of the door and above the door. They must do this in every house where they will eat a lamb.

8That night, they must cook the meat over the fire. They must eat it immediately, with bitter herbs and with bread that has no yeast in it.

9You must cook the meat before you eat it. Cook it over the fire. Do not cook it in water. Cook the whole lamb, with its head, its legs and the inside parts of its body.

10You must eat all the meat before morning arrives. If some of it still remains in the morning, then you must burn it.

11This is how you must eat the lamb: Dress yourselves so that you are ready to travel. Put your shoes on your feet. Take your stick in your hand. Then eat the food quickly. This is the Passover meal which shows that you obey me, the Lord.

12On the night that you eat the Passover meal, I will travel through the country of Egypt. I will kill every firstborn son and every firstborn male animal. I will punish all the gods of Egypt. I am the Lord.

13When you put the blood round the doors of your houses, that will be a sign to show that you live there. When I see the blood on your house, I will pass over you. No trouble will hurt you, when I attack the people of Egypt.
