Leviticus 14:15-18

15The priest shall then take some of the log of oil, pour it in the palm of his own left hand, 16dip his right forefinger into the oil in his palm, and with his finger sprinkle some of it before the Lord seven times. 17The priest is to put some of the oil remaining in his palm on the lobe of the right ear of the one to be cleansed, on the thumb of their right hand and on the big toe of their right foot, on top of the blood of the guilt offering. 18The rest of the oil in his palm the priest shall put on the head of the one to be cleansed and make atonement for them before the Lord.
