23 For the Lord will pass through to strike down the Egyptians; when he sees the blood on the lintel and on the two doorposts, the Lord will pass over that door and will not allow the destroyer to enter your houses to strike you down. 24 You shall observe this rite as a perpetual ordinance for you and your children. 25 When you come to the land that the Lord will give you, as he has promised, you shall keep this observance. 26 And when your children ask you, ‘What do you mean by this observance?’ 27 you shall say, ‘It is the passover sacrifice to the Lord, for he passed over the houses of the Israelites in Egypt, when he struck down the Egyptians but spared our houses.’ ” And the people bowed down and worshiped.

28 The Israelites went and did just as the Lord had commanded Moses and Aaron.
