Leviticus 14:18-20

New Catholic Bible

¹⁸ He shall pour the rest of the oil that is in his hand upon the head of the one who is being cleansed. The priest shall make atonement for him before the Lord. ¹⁹ The priest shall then offer the sin offering and make atonement for the uncleanness of the one who is being cleansed. Afterward he shall slay the burnt offering. ²⁰ The priest shall offer the burnt offering and the cereal offering upon the altar. The priest shall make atonement for him, and he shall be clean.
