Leviticus 15:25-29

²⁵If a woman has a flow of blood for many days that is not in the time of her menstruation, or if she has a flow beyond the time of her menstruation, during all the days of the flow of her uncleanness, she will be as if she were in the days of her period. She is unclean.

²⁶Every bed on which she lies all during her flow of blood will be to her just like the bed on which she lies during her menstruation, and everything on which she sits will be unclean, just like the uncleanness of her menstruation.

²⁷Whoever touches any of those things will be unclean; he must wash his clothes and bathe himself in water, and he will be unclean until evening.

²⁸But if she is cleansed from her flow of blood, then she will count for herself seven days, and after that she will be clean.

²⁹On the eighth day she will take to her two doves or two young pigeons and bring them to the priest at the entrance to the tent of meeting.
