And 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.
Moses went back to his father-in-law, Jethro, and asked permission to visit his brothers in Egypt to check if they were still alive. Jethro agreed and told Moses to go in peace.
