Leviticus 15:16-33

“If a man has an emission of semen, he shall bathe his whole body in water and be unclean until the evening. And every garment and every skin on which the semen comes shall be washed with water and be unclean until the evening. If a man lies with a woman and has an emission of semen, both of them shall bathe themselves in water and be unclean until the evening. “When a woman has a discharge, and the discharge in her body is blood, she shall be in her menstrual impurity for seven days, and whoever touches her shall be unclean until the evening. And everything on which she lies during her menstrual impurity shall be unclean. Everything also on which she sits shall be unclean. And whoever touches her bed shall wash his clothes and bathe himself in water and be unclean until the evening. And whoever touches anything on which she sits shall wash his clothes and bathe himself in water and be unclean until the evening. Whether it is the bed or anything on which she sits, when he touches it he shall be unclean until the evening. And if any man lies with her and her menstrual impurity comes upon him, he shall be unclean seven days, and every bed on which he lies shall be unclean. “If a woman has a discharge of blood for many days, not at the time of her menstrual impurity, or if she has a discharge beyond the time of her impurity, all the days of the discharge she shall continue in uncleanness. As in the days of her impurity, she shall be unclean. Every bed on which she lies, all the days of her discharge, shall be to her as the bed of her impurity. And everything on which she sits shall be unclean, as in the uncleanness of her menstrual impurity. And whoever touches these things shall be unclean, and shall wash his clothes and bathe himself in water and be unclean until the evening. But if she is cleansed of her discharge, she shall count for herself seven days, and after that she shall be clean. And on the eighth day she shall take two turtledoves or two pigeons and bring them to the priest, to the entrance of the tent of meeting. And the priest shall use one for a sin offering and the other for a burnt offering. And the priest shall make atonement for her before the LORD for her unclean discharge. “Thus you shall keep the people of Israel separate from their uncleanness, lest they die in their uncleanness by defiling my tabernacle that is in their midst.” This is the law for him who has a discharge and for him who has an emission of semen, becoming unclean thereby; also for her who is unwell with her menstrual impurity, that is, for anyone, male or female, who has a discharge, and for the man who lies with a woman who is unclean.
