Leviticus 15:16-28

16And if any man’s seed of copulation go out from him, then he shall bathe all his flesh in water, and be unclean until the even. 17And every garment, and every skin, whereon is the seed of copulation, shall be washed with water, and be unclean until the even. 18The woman also with whom a man shall lie with seed of copulation, they shall both bathe themselves in water, and be unclean until the even.

19And if a woman have an issue, and her issue in her flesh be blood, she shall be in her impurity seven days: and whosoever toucheth her shall be unclean until the even. 20And everything that she lieth upon in her impurity shall be unclean: everything also that she sitteth upon shall be unclean. 21And whosoever toucheth her bed shall wash his clothes, and bathe himself in water, and be unclean until the even. 22And whosoever toucheth anything that she sitteth upon shall wash his clothes, and bathe himself in water, and be unclean until the even. 23And if it be on the bed, or on anything whereon she sitteth, when he toucheth it, he shall be unclean until the even. 24And if any man lie with her, and her impurity be upon him, he shall be unclean seven days; and every bed whereon he lieth shall be unclean.

25And if a woman have an issue of her blood many days not in the time of her impurity, or if she have an issue beyond the time of her impurity; all the days of the issue of her uncleanness she shall be as in the days of her impurity: she is unclean. 26Every bed whereon she lieth all the days of her issue shall be unto her as the bed of her impurity: and everything whereon she sitteth shall be unclean, as the uncleanness of her impurity. 27And whosoever toucheth those things shall be unclean, and shall wash his clothes, and bathe himself in water, and be unclean until the even. 28But if she be cleansed of her issue, then she shall number to herself seven days, and after that she shall be clean.
