Exodus 29:14

But the flesh of the calf, and his skin, and his dung, shall you burn with fire without the camp; for it is an [offering on account] of sin.

But the flesh of the bullock, and his skin, and his dung, shalt thou burn with fire without the camp: it is a sin offering.

But the meat of the bull, and its skin, and its dung, you shall burn with fire outside of the camp. It is a sin offering.
