Leviticus 15:25–30

²⁵And if ⁿa woman have an issue of her blood many days out of the time of her separation, or 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. ²⁶Every bed whereon she lieth all the days of her issue shall be unto her as the bed of her separation: and whatsoever she sitteth upon shall be unclean, as the uncleanness of her separation. 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 ^oif 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 ^pturtles, or two young pigeons, and bring them unto the priest, to the door of the tabernacle of the congregation. ³⁰And the priest shall offer the one for a sin offering, and the other for a burnt offering; and the priest shall make an atonement for her before the Lord for the issue of her uncleanness.
