Leviticus 9:8-11 - The Sin Offering For The Priests
8 And Aaron went unto the altar, and slew the calf that was his sin offering. 9 And the sons of Aaron brought the blood unto him, and he dipped his finger in the blood and put it upon the horns of the altar, and poured the blood unto the bottom of the altar. 10 And the fat and the two kidneys with the caul of the liver of the sin offering, he burnt upon the altar, as the LORD commanded Moses: 11 but the flesh and the hide, he burnt with fire without the host.
