Leviticus 15:25-29

²⁵And 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.

²⁶Every 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.

²⁷And whosoever toucheth 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.

²⁹And 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.
