Leviticus 14:14-17

14And the priest shall take of the blood of the trespass-offering, and the priest shall put it on the tip of the right ear of him that is to be cleansed, and on the thumb of his right hand, and on the great toe of his right foot.

15And the priest shall take of the log of oil, and pour it into his, the priest's, left hand;

16and the priest shall dip his right finger in the oil that is in his left hand, and shall sprinkle of the oil with his finger seven times before Jehovah.

17And of the rest of the oil that is in his hand shall the priest put on the tip of the right ear of him that is to be cleansed, and on the thumb of his right hand, and on the great toe of his right foot, upon the blood of the trespass-offering.
