Leviticus 15:25-30

25“When a woman has a discharge of her blood for many days, though it is not the time of her menstruation, or if she has a discharge beyond her period, she will be unclean all the days of her unclean discharge, as she is during the days of her menstruation.

26Any bed she lies on during the days of her discharge will be like her bed during menstrual impurity; any furniture she sits on will be unclean as in her menstrual period.

27Everyone who touches them will be unclean; he must wash his clothes and bathe with water, and he will remain unclean until evening.

28When she is cured of her discharge, she is to count seven days, and after that she will be clean.

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

30The priest is to sacrifice one as a sin offering and the other as a burnt offering. In this way the priest will make atonement for her before the Lord because of her unclean discharge.
