This is what you shall do to them in consecrating them to serve Me as priests: Take a young bull of the herd and two rams without blemish; also unleavened bread, unleavened cakes with oil mixed in, and unleavened wafers spread with oil--make these of choice wheat flour. Place these in one basket and present them in the basket, along with the bull and the two rams. Lead Aaron and his sons up to the entrance of the Tent of Meeting, and wash them with water. Then take the vestments, and clothe Aaron with the tunic, the robe of the ephod, the ephod, and the breastpiece, and gird him with the decorated band of the ephod. Put the headdress on his head, and place the holy diadem upon the headdress. Take the anointing oil and pour it on his head and anoint him. Then bring his sons forward; clothe them with tunics and wind turbans upon them. And gird both Aaron and his sons with sashes. And so they shall have priesthood as their right for all time.
You shall then ordain Aaron and his sons. Lead the bull up to the front of the Tent of Meeting, and let Aaron and his sons lay their hands upon the head of the bull. Slaughter the bull before the Lord, at the entrance of the Tent of Meeting, and take some of the bull's blood and put it on the horns of the altar with your finger; then pour out the rest of the blood at the base of the altar. Take all the fat that covers the entrails, the protuberance on the liver, and the two kidneys with the fat on them, and turn them into smoke upon the altar. The rest of the flesh of the bull, its hide, and its dung shall be put to the fire outside the camp; it is a sin offering.
Next take the one ram, and let Aaron and his sons lay their hands upon the ram's head. Slaughter the ram, and take its blood and dash it against all sides of the altar. Cut up the ram into sections, wash its entrails and legs, and put them with its quarters and its head. Turn all of the ram into smoke upon the altar. It is a burnt offering to the Lord, a pleasing odor, an offering by fire to the Lord.
