Exodus 29:20-21

20Slaughter it, take some of the blood, and put it on the right ear lobes of Aaron and his sons, on their right thumbs, and on the big toes of their right feet. Throw the ⌞rest of the⌟ blood against the altar on all sides.

21Take some of the blood that is on the altar and some of the anointing oil, and sprinkle it on Aaron and his clothes and on his sons and their clothes. In this way Aaron, his sons, and their clothes will be holy.
