Leviticus 15:25-33

²⁵If 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 lies all the days of her issue shall be to her as the bed of her impurity: and everything whereon she sits shall be unclean, as the uncleanness of her impurity. ²⁷Whoever touches 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. ²⁹On the eighth day she shall take to her two turtle-doves, or two young pigeons, and bring them to the priest, to the door of the tent of meeting. ³⁰The 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 Yahweh for the issue of her uncleanness.

³¹Thus shall you separate the children of Israel from their uncleanness, that they not die in their uncleanness, when they defile my tent that is in the midst of them.

³²This is the law of him who has an issue, and of him whose seed of copulation goes from him, so that he is unclean thereby; ³³and of her who is sick with her impurity, and of him who has an issue, of the man, and of the woman, and of him who lies with her who is unclean.
