Leviticus 4:11

“And the skin of the bullock, etc.] Not taken off; for the sin offerings that were burnt were not flayed at all, but were cut in pieces with their skins on them f96; in other burnt offerings the skin was taken off, and was a perquisite of the priest, (<030708>Leviticus 7:8) but this being an offering for the priest, the skin was burnt with the rest: and all his flesh, with his head, and with his legs, and his inwards, and his dung; the burning of these denoted the sufferings of Christ, and these several parts the extent of them, they reaching to all parts of his body as stretched upon the cross; and the dung particularly the reproach of them, he dying the death of the cross, and was made sin…”

“the skin of the bullock, and all his flesh--In ordinary circumstances, these were perquisites of the priests. But in the expiation necessary for a sin of the high priest, after the fat of the sacrifice was offered on the altar, the carcass was carried without the camp [Lev 4:12], in order that the total combustion of it in the place of ashes might the more strikingly indicate the enormity of the transgression, and the horror with which he regarded it (compare Heb 13:12-13).”

“4:11-12 Only the offerings for the priest or the entire community were burned outside the camp. Perhaps this was commanded because the offering had figuratively absorbed the contamination of the high priest or the community and therefore had to be disposed of outside the camp. Those guilty were not to partake of or reap any benefit from their own sin offerings, even if they were priests (6:19-23).”
