Exodus 12:26-27

King James Version

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

²⁷ That ye shall say, It is the sacrifice of the Lord's passover, 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 the head and worshipped.
