Leviticus 4:18-20

New Revised Standard Version, Anglicised

¹⁸ He shall put some of the blood on the horns of the altar that is before the Lord in the tent of meeting; and the rest of the blood he shall pour out at the base of the altar of burnt-offering that is at the entrance of the tent of meeting. ¹⁹ He shall remove all its fat and turn it into smoke on the altar. ²⁰ He shall do with the bull just as is done with the bull of sin-offering; he shall do the same with this. The priest shall make atonement for them, and they shall be forgiven.
