24 And you shall observe this thing for a law to you and to your sons forever.25 And it shall be, when you have come to the land which the LORD will give you, according as He has promised, that you shall keep this service.26 And it will be, when your sons shall say to you, What is this service to you?27 Then you shall say, It [is] the sacrifice of the LORD's passover, who passed over the houses of the sons of Israel in Egypt, when He struck the Egyptians and delivered our houses. And the people bowed and worshiped.
