Leviticus 15:4-8

4Every bed whereon he lieth that hath the flux shall be unclean; and every object on which he sitteth shall be unclean.

5And whoever toucheth his bed shall wash his garments, and bathe in water, and be unclean until the even.

6And he that sitteth on any object whereon he sat that hath the flux shall wash his garments, and bathe in water, and be unclean until the even.

7And he that toucheth the flesh of him that hath the flux shall wash his garments, and bathe in water, and be unclean until the even.

8And if he that hath the flux spit upon him that is clean, then he shall wash his garments, and bathe in water, and be unclean until the even.
