Heb 13:11 For the bodies of those animals whose blood is brought into the holy places by the high priest as a sacrifice for sin are burned outside the camp.
Exodus 29:14 But the flesh of the bull and its skin and its dung you shall burn with fire outside the camp; it is a sin offering.
Leviticus 4:5-7 And the anointed priest shall take some of the blood of the bull and bring it into the tent of meeting, and the priest shall dip his finger in the blood and sprinkle part of the blood seven times before the LORD in front of the veil of the sanctuary. And the priest shall put some of the blood on the horns of the altar of fragrant incense before the LORD that is in the tent of meeting, and all the rest of the blood of the bull he shall pour out at the base of the altar of burnt offering that is at the entrance of the tent of meeting.
Leviticus 4:11-12 But the skin of the bull and all its flesh, with its head, its legs, its entrails, and its dung— all the rest of the bull—he shall carry outside the camp to a clean place, to the ash heap, and shall burn it up on a fire of wood. On the ash heap it shall be burned up.
Leviticus 4:16-21 Then the anointed priest shall bring some of the blood of the bull into the tent of meeting, and the priest shall dip his finger in the blood and sprinkle it seven times before the LORD in front of the veil. And he shall put some of the blood on the horns of the altar that is in the tent of meeting before the LORD, and the rest of the blood he shall pour out at the base of the altar of burnt offering that is at the entrance of the tent of meeting. And all its fat he shall take from it and burn on the altar. Thus shall he do with the bull. As he did with the bull of the sin offering, so shall he do with this. And the priest shall make atonement for them, and they shall be forgiven. And he shall carry the bull outside the camp and burn it up as he burned the first bull; it is the sin offering for the assembly.
