Leviticus 15:5
“And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.”
And this shall be his uncleanness in his issue: whether his flesh run with his issue, or his flesh be stopped from his issue, it is his uncleanness.
Every bed, whereon he lieth that hath the issue, is unclean: and every thing, whereon he sitteth, shall be unclean.
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.
