Exodus 12:1-10, 21-23

GOD said to Moses and Aaron while still in Egypt, “This month is to be the first month of the year for you. Address the whole community of Israel; tell them that on the tenth of this month each man is to take a lamb for his family, one lamb to a house. If the family is too small for a lamb, then share it with a close neighbor, depending on the number of persons involved. Be mindful of how much each person will eat. Your lamb must be a healthy male, one year old; you can select it from either the sheep or the goats. Keep it penned until the fourteenth day of this month and then slaughter it—the entire community of Israel will do this—at dusk. Then take some of the blood and smear it on the two doorposts and the lintel of the houses in which you will eat it. You are to eat the meat, roasted in the fire, that night, along with bread, made without yeast, and bitter herbs. Don’t eat any of it raw or boiled in water; make sure it’s roasted—the whole animal, head, legs, and innards. Don’t leave any of it until morning; if there are leftovers, burn them in the fire.

Moses assembled all the elders of Israel. He said, “Select a lamb for your families and slaughter the Passover lamb. Take a bunch of hyssop and dip it in the bowl of blood and smear it on the lintel and on the two doorposts. No one is to leave the house until morning. GOD will pass through to strike Egypt down. When he sees the blood on the lintel and the two doorposts, GOD will pass over the doorway; he won’t let the destroyer enter your house to strike you down with ruin.
