Exodus 12:24-27

VIN(i) 24 You shall observe this event as a perpetual ordinance for you and your children forever. 25 When you enter the land that the LORD will give you, just as he promised, you are to observe this ritual. 26 »When your children ask you: What does this rite mean to you? 27 you shall say, 'It is the Passover sacrifice to the LORD, who passed over the houses of the Israelites in Egypt when he struck down the Egyptians but spared our houses.'" Then the people bowed down and worshiped.
