Leviticus 15:24-26

²⁴And if any man lie with her, and her impurity be upon him, he shall be unclean seven days; and every bed whereon he lieth shall be unclean.

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.
