Leviticus 15:21-25

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

And whosoever toucheth any thing that she sat upon shall wash his clothes, and bathe himself in water, and be unclean until the even.

And if it be on her bed, or on any thing whereon she sitteth, when he toucheth it, he shall be unclean until the even.

And if any man lie with her at all, and her flowers be upon him, he shall be unclean seven days; and all the bed whereon he lieth shall be unclean.

And if a woman have an issue of her blood many days out of the time of her separation, or if it run beyond the time of her separation; all the days of the issue of her uncleanness shall be as the days of her separation: she shall be unclean.
