Leviticus 14:12-17

12“Then the priest is to take one of the male lambs and offer it as a guilt offering, along with the log of oil; he shall wave them before the Lord as a wave offering.

13He is to slaughter the lamb in the sanctuary area where the sin offering and the burnt offering are slaughtered. Like the sin offering, the guilt offering belongs to the priest; it is most holy.

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.
