Exodus 12:21-28

Revised Standard Version

²¹ Then Moses called all the elders of Israel, and said to them, “Select lambs for yourselves according to your families, and kill the passover lamb. ²² Take a bunch of hyssop and dip it in the blood which is in the basin, and touch the lintel and the two doorposts with the blood which is in the basin; and none of you shall go out of the door of his house until the morning. ²³ For the Lord will pass through to slay the Egyptians; and when he sees the blood on the lintel and on the two doorposts, the Lord will pass over the door, and will not allow the destroyer to enter your houses to slay you. ²⁴ You shall observe this rite as an ordinance for you and for your sons for ever. ²⁵ And when you come to the land which the Lord will give you, as he has promised, you shall keep this service. ²⁶ And when your children say to you, ‘What do you mean by this service?’ ²⁷ you shall say, ‘It is the sacrifice of the Lord’s passover, for he passed over the houses of the people of Israel in Egypt, when he slew the Egyptians but spared our houses.’” And the people bowed their heads and worshiped.

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