Leviticus 9:8-11

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

9The sons of Aaron presented the blood to him. Then he dipped his finger in the blood, dabbed it onto the horns of the altar, and poured out the blood at the base of the altar.

10But the fat, the kidneys and the cover from the liver of the sin offering he burned up as smoke on the altar, as Adonai had commanded Moses.

11The flesh and the hide he burned in a fire outside the camp.
