Leviticus 15:4-8

4Every bed whereon he that hath the issue lieth shall be unclean: and every thing whereon he sitteth shall be unclean.

5And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.

6And he that sitteth on any thing whereon he that hath the issue sat shall wash his clothes, and bathe himself in water, and be unclean until the even.

7And 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.

8And 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.
