Leviticus 15:21

¹⁹And the woman whosoever shall have an issue of blood, when her issue shall be in her body, shall be seven days in her separation; everyone that touches her shall be unclean until evening.

²⁰And everything whereon she shall lie in her separation, shall be unclean; and whatever she shall sit upon, shall be unclean.

— Leviticus 15:21 —

²²And everyone that touches any vessel on which she shall sit, shall wash his garments and bathe himself in water, and shall be unclean until evening.

²³And whether it be while she is on her bed, or on a seat which she may happen to sit upon when he touches her, he shall be unclean till evening.
