Leviticus 15:26

22 Whoever touches any furniture on which she was sitting must wash his clothes and bathe with water, and he will be unclean until evening.

23 And whether it is a bed or furniture on which she was sitting, whoever touches it will be unclean until evening.

24 If 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.

25 When 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.

26 Any 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.

27 Anyone who touches these things will be unclean; he must wash his clothes and bathe with water, and he will be unclean until evening.

28 When a woman is cleansed of her discharge, she must count off seven days, and after that she will be ceremonially clean.

29 On 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.

30 The 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.
