Leviticus 16:27

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.

but into the second, only the high priest enters once a year, not without taking blood, which he offers for himself and for the sins of the people committed in ignorance.

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.
