Leviticus 15:19

¹⁷And every garment, and every skin on which there shall be the seed of copulation shall both be washed with water, and be unclean until evening.

¹⁸And a woman, if a man shall lie with her with seed of copulation—they shall both bathe themselves in water and shall be unclean until evening.

— Leviticus 15:19 —

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

²¹And whosoever shall touch her bed shall wash his garments, and bathe his body in water, and shall be unclean until evening.
