Leviticus 14:23-29

²³On the eighth day they are to take them to the priest at the entrance to the Tent of Meeting before the Lord so they can be made clean.

²⁴The priest will take the lamb for the guilt offering, together with the log of olive oil, and wave them as a wave offering before the Lord.

²⁵After he kills the lamb for the guilt offering, the priest will take some of the blood of the guilt offering and put it on the right earlobe of the one being made clean, on their right thumb, and on the big toe of their right foot.

²⁶Then the priest will pour some of the olive oil into his left palm

²⁷and using his right index finger, will sprinkle some of the oil from his left palm seven times before the Lord.

²⁸The priest shall also put some of the olive oil in his palm on the right earlobe of the person being made clean, on their right thumb, and on the big toe of his right foot, in the same places as the blood of the guilt offering.

²⁹What is left of the olive oil in his palm, the priest will put on the head of the person being made clean and then make them right before the Lord.
