Jethro, Moses' father-in-law, together with Moses' sons and his wife, came to Moses in the desert where he was camping by the mountain of God.

He said to Moses, "I, your father-in-law Jethro, am coming to you, along with your wife and her two sons with her."

You are to take some of the blood that is on the altar and some of the anointing oil and sprinkle it on Aaron, on his garments, on his sons, and on his sons' garments with him, so that he may be holy, he and his garments along with his sons and his sons' garments.
