Leviticus 15:23-25

American Standard Version

²³ And if it be on the bed, or on anything whereon she sitteth, when he toucheth it, he shall be unclean until the even. ²⁴ And 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.

²⁵ And 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.
