LEV 14:29

29 Soothly the priest shall put the tother part of [[the]] oil, that is in his left hand, upon the head of the man that is (to be) cleansed, that he please the Lord for him. (And the priest shall put the rest of the oil, that is in his left hand, on the head of the man that is to be pronounced clean, so that he be made clean before the Lord.)
