Leviticus 14:27-31

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.

The priest shall then put some of the oil that is in his palm 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, on the place of the blood of the guilt offering.

Moreover, the rest of the oil that is in the priest’s palm, he shall put on the head of the one to be cleansed, to make atonement on his behalf before the Lord.

He shall then offer one of the turtledoves or young doves, which are within his means.

He shall offer what he can afford, the one as a sin offering and the other as a burnt offering, together with the grain offering. So the priest shall make atonement before the Lord on behalf of the one to be cleansed.
