Exodus 4:18-20

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