Leviticus 15:24-26

²⁴And if any man should lie with her, and the uncleanness of her separation come upon him, he shall be unclean seven days; and every bed whereon he may lie shall be unclean.

²⁵And if a woman have an issue 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 of her uncleanness shall she be as in the days of her separation; she shall be unclean.

²⁶Every bed whereon she may lie all the days of her issue shall be unto her as the bed of her separation; and whatever vessel she may sit upon shall be unclean, as the uncleanness of her separation.
