Leviticus 4:11

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

The verse lists the remaining body of the bullock as its skin and all its flesh, together with its head and its legs and its inward parts and its dung. When the sin offering was presented for a priest or for the whole congregation, this entire body was to be burned outside the camp. This sin-offering provision was part of what God required in the Mosaic dispensation in addition to the tenth of all increase, for sin offerings and thank offerings were required besides the tenth.
