Exodus 29:19-21

“Then take the second ram. Have Aaron and his sons place their hands on the ram’s head. Slaughter the ram. Take some of its blood and rub it on Aaron’s right earlobe and on the right earlobes of his sons, on the thumbs of their right hands and on the big toes of their right feet. Sprinkle the rest of the blood against all sides of the Altar. Then take some of the blood that is on the Altar, mix it with some of the anointing oil, and splash it on Aaron and his clothes and on his sons and their clothes so that Aaron and his clothes and his sons and his sons’ clothes will be made holy.
