Exodus 29:20-21

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 aanointing oil, and sprinkle it on Aaron and his garments, and on his sons and his sonsgarments with him. He and his garments shall be holy, and his sons and his sonsgarments with him.
