Leviticus 9:8-11 - The Sin Offering For The Priests
8 Aaron then went to the altar and killed the calf of the sin offering, which was for himself. 9 And the sons of Aaron brought 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 bottom of the altar. 10 But he burned the fat and the kidneys and the lobe above the liver of the sin offering on the altar, even as Jehovah commanded Moses. 11 And he burned the flesh and the hide with fire outside the camp.
