Leviticus 15:3-5

American Standard Version

³ 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. ⁴ Every bed whereon he that hath the issue lieth shall be unclean; and everything whereon he sitteth shall be unclean. ⁵ And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.
