Leviticus 15:21

¹⁹And 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.

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

— Leviticus 15:21 —

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

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