Levítico 15

25 And if a woman have an issue (what comes forth) of her blood many days out of the time of her separation, or if it run beyond the time of her separation; all the days of the issue (what comes forth) of her uncleanness shall be as the days of her separation: she [shall be] unclean.

26 Every bed whereon she lies all the days of her issue (what comes forth) shall be unto her as the bed of her separation: and whatsoever she sits upon shall be unclean, as the uncleanness of her separation.

27 And whosoever touches those things shall be unclean, and shall wash his clothes, and bathe [himself] in water, and be unclean until the even.
