And Jethro, Moses' father-in-law, came to Moses with his sons and his wife into the wilderness, where he encamped at the mountain of God.

And he sent word to Moses: I, thy father-in-law Jethro, am come to thee, and thy wife, and her two sons with her.

And thou shalt take of the blood that is upon the altar, and of the anointing oil, and sprinkle it on Aaron, and on his garments, and on his sons, and on the garments of his sons with him; and he shall be hallowed, and his garments, and his sons, and his sons' garments with him.
