Exodus 29:20-21
29:20 and you are to kill the ram and take some of its blood and put it on the tip of the right ear of Aaron, on the tip of the right ear of his sons, on the thumb of their right hand, and on the big toe of their right foot, and then splash the blood all around on the altar.
29:21 You are to take some of the blood that is on the altar and some of the anointing oil and sprinkle it on Aaron, on his garments, on his sons, and on his sons’ garments with him, so that he may be holy, he and his garments along with his sons and his sons’ garments.
