Exodus; Chapter 12; verse 24: “Obey these instructions as a lasting ordinance for you and your descendants. When you enter the land that the LORD will give you as He promised, observe the ceremony. And when your children ask you, ‘What does this ceremony mean to you?’ then tell them, ‘It is the Passover sacrifice to the LORD, who passed over the houses of the Israelites in Egypt and spared our homes when He struck down the Egyptians.”
