Exodus 29:20-21

20Kill the sheep. Put some of its blood on Aaron's right ear, the thumb of his right hand and on the big toe of his right foot. Do the same thing to each of his sons. Then throw some of the sheep's blood onto every side of the altar.

21Mix together some of the blood on the altar and some of the special oil. Splash this onto Aaron and onto his clothes. Splash it also onto his sons and onto their clothes. Then Aaron and his sons and their clothes will be holy.
