Leviticus 4:17-20

¹⁷And the priest shall dip his finger in the blood, and sprinkle seven times in the presence of the Lord before the veil.

¹⁸And some of the blood he shall put upon the horns of the altar that is before the Lord in the tabernacle of ordinance, and all (the rest of the) blood he shall pour out at the foundation of the altar of burnt sacrifice which is at the door of the tabernacle of ordinance.

¹⁹And all the fat he shall separate from him, and sacrifice at the altar.

²⁰And he shall do with the bullock as he did with the bullock of the sin offering, so shall he do with him; and the priest shall atone for them, and it shall be forgiven them.
