Leviticus 15:25-29

²⁵And if a woman shall have an issue of her blood many days out of the time of her separation, or if it shall 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.

²⁶Every bed on which she lieth all the days of her issue shall be to her as the bed of her separation: and whatever she sitteth upon shall be unclean as the uncleanness of her separation.

²⁷And whoever toucheth those things shall be unclean, and shall wash his clothes, and bathe himself in water, and be unclean until the evening.

²⁸But if she shall 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 to her two turtles, or two young pigeons, and bring them to the priest, to the door of the tabernacle of the congregation.
