Exodus 12:26-28

Darby Translation

²⁶ And it shall come to pass, when your children shall say to you, What mean ye by this service?

²⁷ that ye shall say, It is a sacrifice of passover to Jehovah, who passed over the houses of the children of Israel in Egypt when he smote the Egyptians and delivered our houses. And the people bowed their heads and worshipped.

²⁸ And the children of Israel went away, and did as Jehovah had commanded Moses and Aaron; so did they.
