Leviticus 9:8

⁶And Moses said, This is the thing which the Lord has spoken; do it, and the glory of the Lord shall appear among you.

⁷And Moses said to Aaron, Draw nigh to the altar, and offer thy sin offering, and thy whole burnt offering, and make atonement for thyself, and for thy house; and offer the gifts of the people, and make atonement for them, as the Lord commanded Moses.

⁹And the sons of Aaron brought the blood to him, and he dipped his finger into the blood, and put it on the horns of the altar, and he poured out the blood at the bottom of the altar.

¹⁰And he offered up on the altar the fat and the kidneys and the lobe of the liver of the sin offering, according as the Lord commanded Moses.
