Exodus 12:7-13

71Moreover, they shall take some of the blood and put it on the two doorposts and on the lintel 2of the houses in which they eat it. 8They shall eat the flesh 3that same night, 4roasted with fire, and they shall eat it with 5unleavened bread 67and bitter herbs. 9Do not eat any of it raw or boiled at all with water, but rather 8roasted with fire, both its head and its legs along with 9its entrails. 1010And you shall not leave any of it over until morning, but whatever is left of it until morning, you shall completely burn with fire. 11Now you shall eat it in this way: with your garment 11belted around your waist, your sandals on your feet, and your staff in your hand; and you shall eat it in a hurry--it is 12the Lord’s Passover. 12For 13I will go through the land of Egypt on that night, and fatally strike all the firstborn in the land of Egypt, from the human firstborn to animals; and 14against all the gods of Egypt I will execute judgments--15I am the Lord. 1316The blood shall be a sign for you on the houses where you 17live; and when I see the blood I will pass over you, and no plague will come upon you 18to destroy you when I strike the land of Egypt.
