Then Jethro, Moses’ father-in-law, came with his sons and his wife to Moses in the wilderness where he was camped, at the mount of God.

He sent word to Moses, “I, your father-in-law Jethro, am coming to you with your wife and her two sons with her.”

Then you shall take some of the blood that is on the altar and some of the anointing oil, and sprinkle it on Aaron and on his garments and on his sons and on his sons’ garments with him; so he and his garments shall be consecrated, as well as his sons and his sons’ garments with him.
