Leviticus 14:18

16The priest shall dip his right finger in the oil that is in his left hand, and shall sprinkle some of the oil with his finger seven times before the LORD.

17The priest shall put some of the rest of the oil that is in his hand on the tip of the right ear of him who is to be cleansed, and on the thumb of his right hand, and on the big toe of his right foot, upon the blood of the trespass offering.

18The rest of the oil that is in the priest’s hand he shall put on the head of him who is to be cleansed, and the priest shall make atonement for him before the LORD.

19“The priest shall offer the sin offering, and make atonement for him who is to be cleansed because of his uncleanness. Afterward he shall kill the burnt offering;

20then the priest shall offer the burnt offering and the meal offering on the altar. The priest shall make atonement for him, and he shall be clean.
