Exodus 12:26-28

New Revised Standard Version, Anglicised Catholic Edition

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 worshipped.

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