Leviticus 9:8-11 - The Sin Offering For The Priests
8 Then Aaron approached the altar, and he slaughtered the bull calf of the sin offering, which was for himself. 9 Then Aaron's sons presented the blood to him, and he dipped his finger in the blood, and he put [it] on the altar's horns, and he poured out the blood on the altar's base. 10 And the fat and the kidneys and the lobe {from the sin offering's liver} he turned into smoke on the altar, [just] as Yahweh had commanded Moses, 11 but the meat and the skin he burned {with fire} {outside the camp}.
