English: One does not flay.
No flaying — the hide of this chatas bull is not removed.
The High Priest’s chatas bull is not flayed. The hide travels with the flesh, head, legs, innards and dung when the entire animal is carried outside the camp. The prohibition of flaying distinguishes this offering from the olah, whose hide is given to the kohanim.
