Leviticus 14:16

13 And he shall slay the lamb in the place where he shall kill the sin-offering and the burnt-offering, in the holy-place: for as the sin-offering [is] the priest's, [so is] the trespass-offering: it [is] most holy.

14 And the priest shall take [some] of the blood of the trespass-offering, and the priest shall put [it] upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot.

15 And the priest shall take [some] of the log of oil, and pour [it] into the palm of his own left hand:

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

17 And of the rest of the oil that [is] in his hand, shall the priest put upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot, upon the blood of the trespass-offering.

18 And the remnant of the oil that [is] in the priest's hand he shall pour upon the head of him that is to be cleansed: and the priest shall make an atonement for him before the LORD.

19 And the priest shall offer the sin-offering, and make an atonement for him that is to be cleansed from his uncleanness; and afterward he shall kill the burnt-offering.
