Leviticus 14:14-17

14The priest is to take some of the blood from the guilt offering and put it on the right earlobe of the one to be cleansed, on the thumb of his right hand, and on the big toe of his right foot. 15Then the priest shall take some of the log of olive oil, pour it into his left palm, 16dip his right forefinger into the oil in his left palm, and sprinkle some of the oil with his finger seven times before the LORD. 17And the priest is to put some of the oil remaining in his palm on the right earlobe of the one to be cleansed, 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.
