Leviticus 15:24-26

²⁴And if any one shall lie with her, and her uncleanness be upon him, he shall be unclean seven days; and every bed on which he shall have lain shall be unclean.

²⁵And if a woman have an issue of blood many days, not in the time of her separation; if the blood should also flow after her separation, all the days of the issue of her uncleanness shall be as the days of her separation: she shall be unclean.

²⁶And every bed on which she shall lie all the days of her flux shall be to her as the bed of her separation, and every seat whereon she shall sit shall be unclean according to the uncleanness of her separation.
