Anoint them just as you anointed their father, so they may serve me as priests. Their anointing will be to a priesthood that will continue throughout their generations.”
Then Moses took some of the anointing oil and some of the blood from the altar and sprinkled them on Aaron and his garments and on his sons and their garments. So he consecrated Aaron and his garments and his sons and their garments.
Nadab and Abihu, however, died before the Lord when they made an offering with unauthorized fire before him in the Desert of Sinai. They had no sons, so Eleazar and Ithamar served as priests during the lifetime of their father Aaron.
For the law appoints as high priests men in all their weakness; but the oath, which came after the law, appointed the Son, who has been made perfect forever.
