Exodus 12:26-28

Amplified Bible

²⁶ When your children say to you, ‘What does this service mean to you?’ ²⁷ you shall say, ‘It is the sacrifice of the Lord’s Passover, for He passed over the houses of the Israelites in Egypt when He struck the Egyptians, but spared our houses.’” And the people bowed [their heads] low and worshiped [God].

²⁸ Then the Israelites went and did [as they had been told]: just as the Lord had commanded Moses and Aaron, so they did.
