Leviticus 9:8-14

8Aaron therefore went to the altar, and slew the calf of the sin offering, which was for himself. 9And the sons of Aaron brought the blood to him: and he dipped his finger in the blood, and put it upon the horns of the altar, and poured out the blood at the bottom of the altar: 10But the fat, and the kidneys, and the fat above the liver of the sin offering, he burnt upon the altar; as the LORD commanded Moses. 11And the flesh and the hide he burnt with fire outside the camp. 12And he slew the burnt offering; and Aaron’s sons presented to him the blood, which he sprinkled around upon the altar. 13And they presented the burnt offering to him, with the pieces of it, and the head: and he burnt them upon the altar. 14And he washed the inwards and the legs, and burnt them upon the burnt offering on the altar.
