Leviticus 15:25-27

25"If a woman has a discharge of blood for many days, not at the time of her menstrual impurity, or if she has a discharge beyond the time of her impurity, all the days of the discharge she shall continue in uncleanness. As in the days of her impurity, she shall be unclean.

26Every bed on which she lies, all the days of her discharge, shall be to her as the bed of her impurity. And everything on which she sits shall be unclean, as in the uncleanness of her menstrual impurity.

27And whoever touches these things shall be unclean, and shall wash his clothes and bathe himself in water and be unclean until the evening.
