Leviticus 14:15-18

15The priest will then take some of the log of olive oil and pour it into his own left hand.

16Then the priest is to dip his right forefinger into the olive oil that is in his left hand, and sprinkle some of the olive oil with his finger seven times before the Lord.

17The priest will then put some of the rest of the olive oil that is in his hand on the right earlobe of the one being cleansed, on the thumb of his right hand, and on the big toe of his right foot, on the blood of the guilt offering,

18and the remainder of the olive oil that is in his hand the priest is to put on the head of the one being cleansed. So the priest is to make atonement for him before the Lord.
