Leviticus 15:24-26

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

²⁵And if a woman hath a defluxion of blood many days beyond the time of her separation, if it run beyond (the time) of her separation, all the days of the issue of her uncleanness shall be as the days of her separation; she shall be unclean.

²⁶Any bed on which she lieth all the days of her defluxion shall be as the bed of her separation, and everything on which she sitteth shall be unclean as the uncleanness of her separation.
