Leviticus

And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh.

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.

But it shall be on the seventh day, that he shall shave all his hair off his head and his beard and his eyebrows, even all his hair he shall shave off: and he shall wash his clothes, also he shall wash his flesh in water, and he shall be clean.

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

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