Leviticus 14:14-20

14The priest is to take some of the blood of the guilt offering and put it 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. 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. 19“Then the priest is to sacrifice the sin offering and make atonement for the one to be cleansed from their uncleanness. After that, the priest shall slaughter the burnt offering 20and offer it on the altar, together with the grain offering, and make atonement for them, and they will be clean.
