Leviticus 14:23-27

Then on the eighth day he shall bring them for his cleansing to the priest, at the doorway of the tent of meeting, before the Lord.

The priest shall take the lamb of the guilt offering and the log of oil, and the priest shall offer them as a wave offering before the Lord.

Next he shall slaughter the lamb of the guilt offering; and the 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, and on the thumb of his right hand, and on the big toe of his right foot.

The priest shall also pour some of the oil into his left palm;

and with his right-hand finger the priest shall sprinkle some of the oil that is in his left palm seven times before the Lord.
