Leviticus 15:21-27
21 Everyone who touches her bed is to wash his clothes and bathe with water, and he will remain unclean until evening.
22 Everyone who touches any furniture she was sitting on is to wash his clothes and bathe with water, and he will remain unclean until evening.
23 If discharge is on the bed or the furniture she was sitting on, when he touches it he will be unclean until evening.
24 If a man sleeps with her, and blood from her menstruation gets on him, he will be unclean for seven days, and every bed he lies on will become unclean.(A)
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.
26 Any 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.
27 Everyone who touches them will be unclean; he must wash his clothes and bathe with water, and he will remain unclean until evening.
