Leviticus 4:17-20

¹⁷and the priest shall dip his finger in the blood, and sprinkle it seven times before Jehovah, before the veil;

¹⁸and 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.

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

²⁰And 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.
