Exodus 29:20-21

20And you shall slaughter the ram, and take some of its blood and put it on the lobe of Aaron’s right ear and on the lobes of his sons’ right ears, and on the thumbs of their right hands, and on the big toes of their right feet, and sprinkle the rest of the blood around on the altar. 21Then you shall take some of the blood that is on the altar and some of the 1anointing oil, and sprinkle it on Aaron and on his garments, and on his sons and on his sons’ garments with him; so he and his garments shall be consecrated, as well as his sons and his sons’ garments with him.
