Leviticus 4:21

“But the flesh of the bull and its hide and its refuse, you shall burn with fire outside the camp; it is a sin offering.

that is, all the rest of the bull, he shall bring out to a clean place outside the camp where the ashes are poured out, and he shall burn it on wood with fire; where the ashes are poured out it shall be burned.

‘He shall also do with the bull just as he did with the bull of the sin offering; thus he shall do with it. So the priest shall make atonement for them, and they will be forgiven.

‘But no sin offering, of which any of the blood is brought into the tent of meeting to make atonement in the holy place, shall be eaten; it shall be burned with fire.

“And he shall take from the congregation of the sons of Israel two male goats for a sin offering and one ram for a burnt offering.

‘And you shall give it to Eleazar the priest, and it shall be brought outside the camp and be slaughtered in his presence.

For the bodies of those animals whose blood is brought into the holy places by the high priest as an offering for sin, are burned outside the camp.
