Leviticus 14:15-19

The priest shall also take some of the log of oil, and pour it into his left palm;

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

Of the remaining oil which is in his palm, the priest shall put some on the right ear lobe 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 blood of the guilt offering;

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

The priest shall next offer the sin offering and make atonement for the one to be cleansed from his uncleanness. Then afterward, he shall slaughter the burnt offering.
