Leviticus 15:22

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

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

Whoever touches anything that she sits on shall wash his clothes, and bathe himself in water, and be unclean until the evening.
