Leviticus 15:25-26

25And if a woman have an issue of her blood many days not in the time of her impurity, or if she have an issue beyond the time of her impurity; all the days of the issue of her uncleanness she shall be as in the days of her impurity: she is unclean.

26Every bed whereon she lieth all the days of her issue shall be unto her as the bed of her impurity: and every thing whereon she sitteth shall be unclean, as the uncleanness of her impurity.
