Leviticus 4:34-35

New Catholic Bible

³⁴ The priest shall take a bit of the blood of the sin offering with his finger and he shall place it on the horns of the altar of burnt offerings. He shall then pour out the rest of the blood at the base of the altar. ³⁵ He shall take out all of the fat parts, as one takes out the fat parts of a lamb in a peace offering, and he shall burn them on the altar upon the burnt offerings in honor of the Lord. The priest shall make atonement for him and the sin that he committed and he shall be forgiven.
