Leviticus 15:19-30

19When a woman has a discharge consisting of blood from her body, she will be unclean due to her menstruation for seven days, and anyone who touches her will be unclean until evening. 20Anything on which she lies or sits during her menstruation will be unclean, 21and anyone who touches her bed must wash his clothes and bathe with water, and he will be unclean until evening.

22Whoever touches any furniture on which she was sitting must wash his clothes and bathe with water, and he will be unclean until evening. 23And whether it is a bed or furniture on which she was sitting, whoever touches it will be unclean until evening.

24If a man lies with her and her menstrual flow touches him, he will be unclean for seven days, and any bed on which he lies will become unclean.

25When a woman has a discharge of her blood for many days at a time other than her menstrual period, or if it continues beyond her period, she will be unclean all the days of her unclean discharge, just as she is during the days of her menstruation. 26Any bed on which she lies or any furniture on which she sits during the days of her discharge will be unclean, like her bed during her menstrual period. 27Anyone who touches these things will be unclean; he must wash his clothes and bathe with water, and he will be unclean until evening.

28When a woman is cleansed of her discharge, she must count off seven days, and after that she will be ceremonially clean. 29On the eighth day she is to 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 for her unclean discharge.
