Leviticus 4:18-20

Revised Standard Version

¹⁸ And he shall put some of the blood on the horns of the altar which is in the tent of meeting before the Lord; and the rest of the blood he shall pour out at the base of the altar of burnt offering which is at the door of the tent of meeting. ¹⁹ And all its fat he shall take from it and burn upon the altar. ²⁰ Thus shall he do with the bull; as he did with the bull of the sin offering, so shall he do with this; and the priest shall make atonement for them, and they shall be forgiven.
