Exodus 12:24-27

MSB(i) 24 And you are to keep this command as a permanent statute for you and your descendants. 25 When you enter the land that the LORD will give you as He promised, you are to keep this service. 26 When your children ask you, ‘What does this service mean to you?’ 27 you are to reply, ‘It is the Passover sacrifice to the LORD, who passed over the houses of the Israelites in Egypt when He struck down the Egyptians and spared our homes.’” Then the people bowed down and worshiped.
