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 ... returned to Jethro. Being in his service, it was right to obtain his consent; but Moses evinced piety, humility, and prudence, in not divulging the special object of his journey.
