Leviticus 15:19-24

19And if a woman have an issue, and her issue in her flesh be blood, she shall be in her impurity seven days: and whosoever toucheth her shall be unclean until the even.

20And every thing that she lieth upon in her impurity shall be unclean: every thing also that she sitteth upon shall be unclean.

21And whosoever toucheth her bed shall wash his clothes, and bathe himself in water, and be unclean until the even.

22And whosoever toucheth any thing that she sitteth upon shall wash his clothes, and bathe himself in water, and be unclean until the even.

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

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.
