24 And ye shall observe this thing for an ordinance to thee and to thy sons forever.25 And it shall come to pass, when ye have entered into the land which the LORD will give you, according as he has promised, that ye shall keep this service.26 And it shall come to pass, when your children shall say unto you, What do you mean by this service?27 That ye 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 smote the Egyptians and delivered our houses. Then the people bowed and worshipped.
