'Refuse' in the Bible

But the hide of the bull and all its flesh with its head and its legs and its entrails and its refuse,

But the bull and its hide and its flesh and its refuse he burned in the fire outside the camp, just as the Lord had commanded Moses.

But the bull of the sin offering and the goat of the sin offering, whose blood was brought in to make atonement in the holy place, shall be taken outside the camp, and they shall burn their hides, their flesh, and their refuse in the fire.
