Anoint them just as you anointed their father, so that they may also serve Me as priests. Their anointing will serve to inaugurate a permanent priesthood for them throughout their generations.”
Then Moses took some of the anointing oil and some of the blood that was on the altar and sprinkled them on Aaron and his garments, as well as on his sons and their garments. In this way he consecrated Aaron and his garments, as well as his sons and their garments.
But Nadab and Abihu died in the Lord’s presence when they presented unauthorized fire before the Lord in the Wilderness of Sinai, and they had no sons. So Eleazar and Ithamar served as priests under the direction of Aaron their father.
For the law appoints as high priests men who are weak, but the promise of the oath, which came after the law, appoints a Son, who has been perfected forever.
