Leviticus 14:18

¹⁶And he shall dip with the finger of his right hand into some of the oil that is in his left hand, and he shall sprinkle with his finger seven times before the Lord.

¹⁷And the remaining oil that is in his hand, the priest shall put on the tip of the right ear of him that is under cleansing, and on the thumb of his right hand, and on the great toe of his right foot, on the place of the blood of the trespass offering.

— Leviticus 14:18 —

¹⁹And the priest shall sacrifice the sin offering, and the priest shall make atonement for the person under purification to cleanse him from his sin, and afterward the priest shall slay the whole burnt offering.

²⁰And the priest shall offer the whole burnt offering, and the sacrifice upon the altar before the Lord; and the priest shall make atonement for him, and he shall be cleansed.
