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 burn with fire. 11Now you shall eat it in this manner: with your loins girded, your sandals on your feet, and your staff in your hand; and you shall eat it in haste--it is 11the Lord’s Passover. 12For 12I will go through the land of Egypt on that night, and will strike down all the firstborn in the land of Egypt, both man and beast; and 13against all the gods of Egypt I will execute judgments--14I am the Lord. 1315The blood shall be a sign for you on the houses where you 16live; and when I see the blood I will pass over you, and no plague will befall you 17to destroy you when I strike the land of Egypt.
