Leviticus 4:34-35

Darby Translation

³⁴ And the priest shall take of the blood of the sin-offering with his finger, and put [it] on the horns of the altar of burnt-offering, and shall pour out all the blood thereof at the bottom of the altar.

³⁵ And he shall take away all the fat thereof, as the fat of the lamb is taken away from the sacrifice of peace-offering; and the priest shall burn them on the altar, with Jehovah's offerings by fire; and the priest shall make atonement for him concerning his sin which he hath sinned, and it shall be forgiven him.
