21 Then Moses called all the elders of Israel and said to them, “Go and select lambs for yourselves daccording to your clans, and kill the Passover lamb. 22 Take a bunch of ehyssop and fdip it in the blood that is in the basin, and touch gthe lintel and the two doorposts with the blood that is in the basin. hNone of you shall go out of the door of his house until the morning. 23 iFor the Lord will pass through to strike the Egyptians, and when he sees the blood on gthe lintel and on the two doorposts, the Lord will pass over the door and jwill not allow the destroyer to enter your houses to strike you. 24 You shall observe this rite as a statute for you and for your sons forever. 25 And when you come to the land that the Lord will give you, kas he has promised, you shall keep this service. 26 And lwhen your children say to you, ‘What do you mean by this service?’ 27 you shall say, m‘It is the sacrifice of the Lord’s Passover, for he passed over the houses of the people of Israel in Egypt, when he struck the Egyptians but spared our houses.’ ” And the people nbowed their heads and worshiped.
29 oAt midnight the pLord struck down all the firstborn in the land of Egypt, qfrom 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 the livestock. 30 And Pharaoh rose up in the night, he and all his servants and all the Egyptians. And there was ra great cry in Egypt, for there was not a house where someone was not dead.
