Leviticus 8
14 Ref He brought the bull of the sin offering, and Aaron and his sons laid their hands on the head of the bull of the sin offering.
15 Ref He killed it; and Moses took the blood, and put it on the horns of the altar round about with his finger, and purified the altar, and poured out the blood at the base of the altar, and sanctified it, to make atonement for it.
16 Ref He took all the fat that was on the innards, and the cover of the liver, and the two kidneys, and their fat; and Moses burned it on the altar.
17 Ref But the bull, and its skin, and its flesh, and its dung, he burned with fire outside the camp; as Yahweh commanded Moses.
