Leviticus 15:19-33

And 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. And everything that she lieth upon in her impurity shall be unclean: everything also that she sitteth upon shall be unclean. And whosoever toucheth her bed shall wash his clothes, and bathe himself in water, and be unclean until the even. And whosoever toucheth anything that she sitteth upon shall wash his clothes, and bathe himself in water, and be unclean until the even. And if it be on the bed, or on anything whereon she sitteth, when he toucheth it, he shall be unclean until the even. And 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. And 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. Every 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. And whosoever toucheth those things shall be unclean, and shall wash his clothes, and bathe himself in water, and be unclean until the even. But if she be cleansed of her issue, then she shall number to herself seven days, and after that she shall be clean. And on the eighth day she shall take unto her two turtle-doves, or two young pigeons, and bring them unto the priest, to the door of the tent of meeting. And the priest shall offer the one for a sin-offering, and the other for a burnt-offering; and the priest shall make atonement for her before Jehovah for the issue of her uncleanness. Thus shall ye separate the children of Israel from their uncleanness, that they die not in their uncleanness, when they defile my tabernacle that is in the midst of them. This is the law of him that hath an issue, and of him whose seed of copulation goeth from him, so that he is unclean thereby; and of her that is sick with her impurity, and of him that hath an issue, of the man, and of the woman, and of him that lieth with her that is unclean.
