Exodus 29:5-14

“Then take the vestments and dress Aaron in the tunic, the robe of the Ephod, the Ephod, and the Breastpiece, belting the Ephod on him with the embroidered waistband. Set the turban on his head and place the sacred crown on the turban. Then take the anointing oil and pour it on his head, anointing him. Then bring his sons, put tunics on them and gird them with sashes, both Aaron and his sons, and set hats on them. Their priesthood is upheld by law and is permanent. “This is how you will ordain Aaron and his sons: Bring the bull to the Tent of Meeting. Aaron and his sons will place their hands on the head of the bull. Then you will slaughter the bull in the presence of GOD at the entrance to the Tent of Meeting. Take some of the bull’s blood and smear it on the horns of the Altar with your finger; pour the rest of the blood on the base of the Altar. Next take all the fat that covers the innards, fat from around the liver and the two kidneys, and burn it on the Altar. But the flesh of the bull, including its hide and dung, you will burn up outside the camp. It is an Absolution-Offering.
