Leviticus

And the skin of the bullock, and all his flesh, with his head, and with his legs, and his inwards, and his dung,

Even the whole bullock shall he carry forth without the camp unto a clean place, where the ashes are poured out, and burn him on the wood with fire: where the ashes are poured out shall he be burnt.

But the bullock, and his hide, his flesh, and his dung, he burnt with fire without the camp; as the Lord commanded Moses.

For the bodies of those beasts, whose blood is brought into the sanctuary by the high priest for sin, are burned without the camp.

And the bullock for the sin offering, and the goat for the sin offering, whose blood was brought in to make atonement in the holy place, shall one carry forth without the camp; and they shall burn in the fire their skins, and their flesh, and their dung.
