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.

"And you, bring near to you your brother Aaron and his sons with him from among the Israelites, so that they may minister as my priests -- Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.

and wrap the sashes around Aaron and his sons and put headbands on them, and so the ministry of priesthood will belong to them by a perpetual ordinance. Thus you are to consecrate Aaron and his sons.

and you then take his daughters for your sons, and when his daughters prostitute themselves to their gods, they will make your sons prostitute themselves to their gods as well.
