Leviticus 15:25-30

25“‘When a woman’s discharge of blood flows many days not at the time of her menstruation, or if it flows beyond the time of her menstruation, all the days of her discharge of impurity will be like the days of her menstruation – she is unclean.

26Any bed she lies on all the days of her discharge will be to her like the bed of her menstruation, any furniture she sits on will be unclean like the impurity of her menstruation,

27and anyone who touches them will be unclean, and he must wash his clothes, bathe in water, and be unclean until evening.

28“‘If she becomes clean from her discharge, then she is to count off for herself seven days, and afterward she will be clean.

29Then on the eighth day she must take for herself two turtledoves or two young pigeons and she must bring them to the priest at the entrance of the Meeting Tent,

30and the priest is to make one a sin offering and the other a burnt offering. So the priest is to make atonement for her before the Lord from her discharge of impurity.
