Leviticus 14:13-14:20

The lamb shall be slaughtered at the spot in the sacred area where the sin offering and the burnt offering are slaughtered. For the guilt offering, like the sin offering, goes to the priest; it is most holy. The priest shall take some of the blood of the guilt offering, and the priest shall put it on the ridge of the right ear of him who is being cleansed, and on the thumb of his right hand, and on the big toe of his right foot. The priest shall then take some of the log of oil and pour it into the palm of his own left hand. And the priest shall dip his right finger in the oil that is in the palm of his left hand and sprinkle some of the oil with his finger seven times before the Lord. Some of the oil left in his palm shall be put by the priest on the ridge of the right ear of the one being cleansed, on the thumb of his right hand, and on the big toe of his right foot--over the blood of the guilt offering. The rest of the oil in his palm the priest shall put on the head of the one being cleansed. Thus the priest shall make expiation for him before the Lord. The priest shall then offer the sin offering and make expiation for the one being cleansed of his uncleanness. Last, the burnt offering shall be slaughtered, and the priest shall offer the burnt offering and the meal offering on the altar, and the priest shall make expiation for him. Then he shall be clean.
