Exodus 29:19-22

19"You shall take the other ram, and Aaron and his sons shall lay their hands on the head of the ram,

20and you shall kill the ram and take part of its blood and put it on the tip of the right ear of Aaron and on the tips of the right ears of his sons, and on the thumbs of their right hands and on the great toes of their right feet, and throw the rest of the blood against the sides of the altar.

21Then 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.

22"You shall also take the fat from the ram and the fat tail and the fat that covers the entrails, and the long lobe of the liver and the two kidneys with the fat that is on them, and the right thigh (for it is a ram of ordination),
