and he said to Aaron, “Take for yourself a bull calf for a sin offering and a ram for a burnt offering, both without blemish, and offer them before the Lord.
if it is the anointed priest who sins, thus bringing guilt on the people, then he shall offer for the sin that he has committed a bull from the herd without blemish to the Lord for a sin offering.
Then you shall take part of the blood that is on the altar, and of the anointing oil, and sprinkle it on Aaron and his garments, and on his sons and his sons’ garments with him. He and his garments shall be holy, and his sons and his sons’ garments with him.
And you shall put them on Aaron your brother, and on his sons with him, and shall anoint them and ordain them and consecrate them, that they may serve me as priests.
For in six days the Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy.
“Then bring near to you Aaron your brother, and his sons with him, from among the people of Israel, to serve me as priests—Aaron and Aaron’s sons, Nadab and Abihu, Eleazar and Ithamar.
