Exodus 12:21-30

21Then 1Moses called for all the elders of Israel and said to them, “Go and 2take for yourselves 3lambs according to your families, and slaughter 4the Passover lamb. 22And 5you shall take a bunch of hyssop and dip it in the blood which is in the basin, and 6apply some of the blood that is in the basin to the lintel and the two doorposts; and none of you shall go outside the door of his house until morning. 23For 7the Lord will pass through to strike the Egyptians; but when He sees the blood on the lintel and on the two doorposts, the Lord will pass over the door and will 8not allow the 9destroyer to come in to your houses to strike you. 24And 10you shall keep this event as an ordinance for you and your children forever. 25When you enter the land which the Lord will give you, as He has 11promised, you shall keep this 12rite. 2613And when your children say to you, ‘14What does this rite mean to you?’ 27then you shall say, ‘It is a Passover sacrifice to 15the Lord because He passed over the houses of the sons of Israel in Egypt when He struck the Egyptians, but 16spared our homes.’” 17And the people bowed low and worshiped.

28Then the sons of Israel went and did so; just as the Lord had commanded Moses and Aaron, so they did.

29Now it came about at 18midnight that 19the Lord struck all 20the firstborn in the land of Egypt, from the firstborn of Pharaoh who sat on his throne to the firstborn of the captive who was in the dungeon, and all the firstborn of 21cattle. 30And Pharaoh got up in the night, he and all his servants and all the Egyptians, and there was 22a great cry in Egypt, for there was no home where there was not someone dead.
