Exodus 4:18-20

18And Moses went and returned to Jethro his father in law, and said unto him, Let me go, I pray thee, and return unto my brethren which are in Egypt, and see whether they be yet alive. And Jethro said to Moses, Go in peace.1 19And the Lord said unto Moses in Midian, Go, return into Egypt: for all the men are dead which sought thy life. 20And Moses took his wife and his sons, and set them upon an ass, and he returned to the land of Egypt: and Moses took the rod of God in his hand.
