Leviticus 9:6-10

⁶Moses said, “This is the thing which the LORD commanded that you should do; and the LORD’s glory shall appear to you.”

⁷Moses said to Aaron, “Draw near to the altar, and offer your sin offering, and your burnt offering, and make atonement for yourself, and for the people; and offer the offering of the people, and make atonement for them, as the LORD commanded.”

⁸So Aaron came near to the altar, and killed the calf of the sin offering, which was for himself.

⁹The sons of Aaron presented the blood to him; and he dipped his finger in the blood, and put it on the horns of the altar, and poured out the blood at the base of the altar;

¹⁰but the fat, and the kidneys, and the cover from the liver of the sin offering, he burned upon the altar, as the LORD commanded Moses.
