Leviticus 15:25-30

25“Now if a woman has a discharge of her blood for many days not during her niddah or if she has a discharge beyond the time of her niddah all the days of the discharge of her uncleanness shall be as in the days of her niddah . She is unclean.

26Every bed where she lies all the days of her discharge will be like her bed during her niddah , and everything she sits on will become unclean like the uncleanness of her niddah .

27Whoever touches these things will become unclean and is to wash his clothes and bathe himself in water, and be unclean until the evening.

28“But if she is cleansed of her discharge, then she is to count off seven days for herself, and after that she will be clean.

29On the eighth day she is to take two turtledoves or two young pigeons, and bring them to the kohen, at the entrance of the Tent of Meeting.

30The kohen is to offer the one for a sin offering, and the other for a burnt offering. So the kohen will make atonement for her before Adonai for the uncleanness of her discharge.
