Leviticus 4:29-31

New Revised Standard Version, Anglicised

²⁹ You shall lay your hand on the head of the sin-offering; and the sin-offering shall be slaughtered at the place of the burnt-offering. ³⁰ The priest shall take some of its blood with his finger and put it on the horns of the altar of burnt-offering, and he shall pour out the rest of its blood at the base of the altar. ³¹ He shall remove all its fat, as the fat is removed from the offering of well-being, and the priest shall turn it into smoke on the altar for a pleasing odour to the Lord. Thus the priest shall make atonement on your behalf, and you shall be forgiven.
