Leviticus 14:26-29

26 The priest is to pour some of the oil into the palm of his own left hand,
27 and with his right forefinger sprinkle some of the oil from his palm seven times before the LORD.
28 Some of the oil in his palm he is to put on the same places he put the blood of the guilt offering—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.
29 The rest of the oil in his palm the priest shall put on the head of the one to be cleansed, to make atonement for them before the LORD.
