Numbers 19:7

And whosoever beareth ought of the carcass of them shall wash his clothes, and be unclean until the even.

And he that is to be cleansed shall wash his clothes, and shave off all his hair, and wash himself in water, that he may be clean: and after that he shall come into the camp, and shall tarry abroad out of his tent seven days.

And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.

And he that let go the goat for the scapegoat shall wash his clothes, and bathe his flesh in water, and afterward come into the camp. And the bullock for the sin offering, and the goat for the sin offering, whose blood was brought in to make atonement in the holy place, shall one carry forth without the camp; and they shall burn in the fire their skins, and their flesh, and their dung. And he that burneth them shall wash his clothes, and bathe his flesh in water, and afterward he shall come into the camp.

And he that burneth her shall wash his clothes in water, and bathe his flesh in water, and shall be unclean until the even.
