Leviticus 14:12-17

12Then the priest shall take one of the male lambs and offer it as a guilt offering, with the log of oil, and present them as a wave offering before the Lord.

13He shall kill the male lamb in the place where they kill the sin offering and the burnt offering, in the sacred place [the courtyard of the tabernacle]; for the guilt offering, like the sin offering, belongs to the priest; it is most holy.

14The priest shall 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.

15The priest shall also take some of the log of oil, and pour it into the palm of his own left hand;

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

17Of the rest of the oil which is in his palm, the priest shall put some 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 top of the blood of the guilt offering.
