Leviticus 14:18

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:

20 And the priest shall offer the burnt offering and the meat offering upon the altar: and the priest shall make an atonement for him, and he shall be clean.

21 And if he [be] poor, and cannot get so much; then he shall take one lamb [for] a trespass offering to be waved, to make an atonement for him, and one tenth deal of fine flour mingled with oil for a meat offering, and a log of oil;
