Leviticus 6:11

‘If his offering is a burnt offering from the herd, he shall bring it near, a male without blemish; he shall bring it near to the doorway of the tent of meeting, that he may be accepted before Yahweh.

‘And the sons of Aaron the priest shall put fire on the altar and arrange wood on the fire.

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.
