[17] And every garment, and every skin, whereon is the seed of copulation, shall be washed with water, and be unclean until the even. [18] The woman also with whom man shall lie with seed of copulation, they shall both bathe themselves in water, and be unclean until the even. [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.
