Exodus 29:20-21

20and thou shalt slaughter the ram, and take of its blood, and put [it] on the tip of the [right] ear of Aaron, and on the tip of the right ear of his sons, and on the thumb of their right hand, and on the great toe of their right foot; and thou shalt sprinkle the blood upon the altar round about.

21And thou shalt take of the blood that is upon the altar, and of the anointing oil, and sprinkle [it] on Aaron, and on his garments, and on his sons, and on the garments of his sons with him; and he shall be hallowed, and his garments, and his sons, and his sons' garments with him.
