Leviticus 15:19-24King James Version (KJV)
19 And if a woman have an issue, and her issue in her flesh be blood, she shall be put apart seven days: and whosoever toucheth her shall be unclean until the even.
20 And every thing that she lieth upon in her separation shall be unclean: every thing also that she sitteth upon shall be unclean.
21 And whosoever toucheth her bed shall wash his clothes, and bathe himself in water, and be unclean until the even.
22 And whosoever toucheth any thing that she sat upon shall wash his clothes, and bathe himself in water, and be unclean until the even.
23 And if it be on her bed, or on any thing whereon she sitteth, when he toucheth it, he shall be unclean until the even.
24 And if any man lie with her at all, and her flowers be upon him, he shall be unclean seven days; and all the bed whereon he lieth shall be unclean.
