Leviticus 4:18-20

Darby Translation

¹⁸ and he shall put of the blood on the horns of the altar that is before Jehovah which is in the tent of meeting; and he shall pour out all the blood at the bottom of the altar of burnt-offering, which is at the entrance of the tent of meeting.

¹⁹ And all its fat shall he take off from it and burn on the altar.

²⁰ And he shall do with the bullock as he did with the bullock of sin-offering: so shall he do with it. And the priest shall make atonement for them; and it shall be forgiven them.
