12 that thou shalt set apart unto the Lord all that openeth the womb, and every firstling which thou hast that cometh of a beast; the males shall be the Lord'S.
13 And every firstling of an ass thou shalt redeem with a lamb; and if thou wilt not redeem it, then thou shalt break its neck: and all the firstborn of man among thy sons shalt thou redeem.
14 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 the Lord brought us out from Egypt, from the house of bondage:
15 and it came to pass, when Pharaoh would hardly let us go, that the Lord slew all the firstborn in the land of Egypt, both the firstborn of man, and the firstborn of beast: therefore I sacrifice to the Lord all that openeth the womb, being males; but all the firstborn of my sons I redeem.
16 And it shall be for a sign upon thine hand, and for frontlets between thine eyes: for by strength of hand the Lord brought us forth out of Egypt.
17 And it came to pass, when Pharaoh had let the people go, that God led them not by the way of the land of the Philistines, although that was near; for God said, Lest peradventure the people repent when they see war, and they return to Egypt:
18 but God led the people about, by the way of the wilderness by the Red Sea: and the children of Israel went up armed out of the land of Egypt.
