Exodus 12:26-28

Wycliffe Bible

²⁶ and when your sons shall say to you, What is this religion? (What is the meaning of this rite?)

²⁷ ye shall say to them, It is the sacrifice of the passing (over) of the Lord, when he passed over the houses of the sons of Israel in Egypt, and smote the Egyptians, and delivered our houses (but spared our houses). And the people was bowed, and worshipped.

²⁸ And the sons of Israel went out (And the Israelites went out), and did as the Lord commanded to Moses and Aaron.
