Leviticus 4:34-35

Christian Standard Bible

³⁴ Then the priest is to take some of the blood of the sin offering with his finger and apply it to the horns of the altar of burnt offering. He is to pour out the rest of its blood at the base of the altar. ³⁵ He is to remove all its fat just as the fat of the lamb is removed from the fellowship sacrifice. The priest will burn it on the altar along with the food offerings to the Lord. In this way the priest will make atonement on his behalf for the sin he has committed, and he will be forgiven.
