Leviticus 8:14-17

¹⁴And Moses brought near the calf for the sin offering, and Aaron and his sons laid their hands on the head of the calf of the sin offering.

¹⁵And he slew it; and Moses took of the blood, and put it on the horns of the altar round about with his finger; and he purified the altar, and poured out the blood at the bottom of the altar, and sanctified it, to make atonement upon it.

¹⁶And Moses took all the fat that was upon the innards, and the lobe on the liver, and both the kidneys, and the fat that was upon them, and Moses offered them on the altar.

¹⁷But the calf, and his hide, and his flesh, and his dung, he burned with fire without the camp, as the Lord commanded Moses.
