Leviticus 4:10-12

¹⁰as it was taken off from the bullock of the sacrifice of peace offerings: and the priest shall burn them upon the altar of the burnt offering.

¹¹And the skin of the bullock, and all his flesh, with his head, and with his legs, and his inwards, and his dung,

¹²even 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.
