Leviticus 15:5-9

And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.

And he that sitteth on any thing whereon he sat that hath the issue shall wash his clothes, and bathe himself in water, and be unclean until the even.

And he that toucheth the flesh of him that hath the issue shall wash his clothes, and bathe himself in water, and be unclean until the even.

And if he that hath the issue spit upon him that is clean; then he shall wash his clothes, and bathe himself in water, and be unclean until the even.

And what saddle soever he rideth upon that hath the issue shall be unclean.
