Exodus 12
21 Ref Then Moses sent for the chiefs of Israel, and said to them, See that lambs are marked out for yourselves and your families, and let the Passover lamb be put to death.
22 Ref And take some hyssop and put it in the blood in the basin, touching the two sides and the top of the doorway with the blood from the basin; and let not one of you go out of his house till the morning.
23 Ref For the Lord will go through the land, sending death on the Egyptians; and when he sees the blood on the two sides and the top of the door, the Lord will go over your door and will not let death come in for your destruction.
24 Ref And you are to keep this as an order to you and to your sons for ever.
25 Ref And when you come into the land which the Lord will make yours, as he gave his word, you are to keep this act of worship.
26 Ref And when your children say to you, What is the reason of this act of worship?
27 Ref Then you will say, This is the offering of the Lord's Passover; for he went over the houses of the children of Israel in Egypt, when he sent death on the Egyptians, and kept our families safe. And the people gave worship with bent heads.
28 Ref And the children of Israel went and did so; as the Lord had given orders to Moses and Aaron, so they did.
29 Ref And in the middle of the night the Lord sent death on every first male child in the land of Egypt, from the child of Pharaoh on his seat of power to the child of the prisoner in the prison; and the first births of all the cattle.
30 Ref Then Pharaoh got up in the night, he and all his servants and all the Egyptians; and a great cry went up from Egypt; for there was not a house where someone was not dead.
