Leviticus 15:25-29

²⁵And if a woman hath a defluxion of blood many days beyond the time of her separation, if it 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.

²⁶Any bed on which she lieth all the days of her defluxion shall be as the bed of her separation, and everything on which she sitteth shall be unclean as the uncleanness of her separation.

²⁷And whoso toucheth them shall be unclean, and shall wash his clothes, and bathe in water, and be unclean until evening.

²⁸But if she be cleansed form her defluxion, then let her number to herself seven days, and afterward she is clean.

²⁹And on the eighth day let her take or herself two turtle doves, or two young pigeons, and bring them to the priest at the door of the tabernacle of ordinance.
