Leviticus 15:3-7

³And this shall be his uncleanness in his flux: whether his flesh run with his flux, or his flesh be closed from his flux, it is his uncleanness.

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.
