Leviticus 14:24-26

²⁴And the priest shall take the lamb of the trespass-offering, and the log of oil, and the priest shall wave them for a wave-offering before the LORD.

²⁵And he shall kill the lamb of the trespass-offering, and the priest shall take some of the blood of the trespass-offering, and put it upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot.

²⁶And the priest shall pour of the oil into the palm of his own left hand.
