Exodus 13:11-21

11And it shall be when Yhwh shall bring thee into the land of the Canaanites, as he sware unto thee and to thy fathers, and shall give it thee, 12That thou shalt set apart unto Yhwh all that openeth the matrix, and every firstling that cometh of a beast which thou hast; the males shall be Yhwh's.1 13And every firstling of a donkey thou shalt redeem with a lamb; and if thou wilt not redeem it, then thou shalt break his neck: and all the firstborn of man among thy children shalt thou redeem.2

17And it came to pass, when Pharaoh had let the people go, that God led them not through 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: 18But God led the people about, through the way of the wilderness of the Red sea: and the children of Israel went up armed out of the land of Egypt.4 19And Moses took the bones of Joseph with him: for he had straitly sworn the children of Israel, saying, God will surely visit you; and ye shall carry up my bones away hence with you.

20And they took their journey from Succoth, and encamped in Etham, in the edge of the wilderness. 21And Yhwh went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night:
