Leviticus 15:16-28

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

19And if a woman shall have an issue, and her issue in her flesh be blood, she shall be put apart seven days: and whoever toucheth her shall be unclean until the evening.1 20And every thing that she lieth upon in her separation shall be unclean: every thing also that she sitteth upon shall be unclean. 21And whoever toucheth her bed shall wash his clothes, and bathe himself in water, and be unclean until the evening. 22And whoever toucheth any thing that she sat upon shall wash his clothes, and bathe himself in water, and be unclean until the evening. 23And if it be on her bed, or on any thing on which she sitteth, when he toucheth it, he shall be unclean until the evening. 24And if any man shall lie with her at all, and her impurity be upon him, he shall be unclean seven days; and all the bed on which he lieth shall be unclean. 25And if a woman shall have an issue of her blood many days out of the time of her separation, or if it shall 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. 26Every bed on which she lieth all the days of her issue shall be to her as the bed of her separation: and whatever she sitteth upon shall be unclean, as the uncleanness of her separation. 27And whoever toucheth those things shall be unclean, and shall wash his clothes, and bathe himself in water, and be unclean until the evening. 28But if she shall be cleansed of her issue, then she shall number to herself seven days, and after that she shall be clean.
