Leviticus 8:14-17

14And he brought near the bullock for the sin-offering; and Aaron and his sons laid their hands on the head of the bullock for the sin-offering;

15and he slaughtered [it], and Moses took the blood, and put [it] on the horns of the altar round about with his finger, and cleansed the altar from sin, and the blood he poured at the bottom of the altar, and hallowed it, making atonement for it.

16And he took all the fat that was on the inwards, and the net of the liver, and the two kidneys, and their fat, and Moses burned [them] on the altar.

17And the bullock, and its skin, and its flesh, and its dung he burned with fire outside the camp, as Jehovah had commanded Moses.
