And it shall come to pass, when your children shall say unto you, What mean ye by this service?that ye shall say, It is the sacrifice of Jehovah’s passover, who passed over the houses of the children of Israel in Egypt, when he smote the Egyptians, and delivered our houses. And the people bowed the head and worshipped.
And it shall be, when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto him, By strength of hand Jehovah brought us out from Egypt, from the house of bondage:and it came to pass, when Pharaoh would hardly let us go, that Jehovah slew all the first- born in the land of Egypt, both the first- born of man, and the first- born of beast: therefore I sacrifice to Jehovah all that openeth the womb, being males; but all the first- born of my sons I redeem.
