Leviticus 14:14-18

The priest shall take some of the blood of the guilt offering, and the priest shall put it on the lobe of the right ear of him who is to be cleansed and on the thumb of his right hand and on the big toe of his right foot. Then the priest shall take some of the log of oil and pour it into the palm of his own left hand and dip his right finger in the oil that is in his left hand and sprinkle some oil with his finger seven times before the LORD. And some of the oil that remains in his hand the priest shall put on the lobe of the right ear of him who is to be cleansed and on the thumb of his right hand and on the big toe of his right foot, on top of the blood of the guilt offering. And the rest of the oil that is in the priest’s hand he shall put on the head of him who is to be cleansed. Then the priest shall make atonement for him before the LORD.
