For of the animals whose “blood is brought” by the high priest “into the Holy of Holies” concerning sin, of these the bodies “are burned outside the camp”. Lev. 16:2, 27
And the bull of the sin offering, and the goat of the sin offering, whose blood has been brought in to atone in the sanctuary, one shall carry them out to the outside of the camp; and they shall burn their skins with fire, and their flesh, and their dung.
And any sin offering of its blood that is brought into the tabernacle of the congregation to make atonement in the sanctuary, it shall not be eaten. It shall be burned with fire.
and Aaron’s sons brought the blood near to him, and he dipped his finger in the blood and put it on the horns of the altar. And he poured out the blood at the base of the altar;
Then the priest shall wash his clothes, and he shall bathe his flesh in water, and afterward he may come into the camp; and the priest shall be unclean until the evening.
