Leviticus 11:32-36

32When one of them dies and falls on something, that article becomes unclean; any article of wood, clothing, leather, sackcloth, or any implement used for work must be rinsed with water and will remain unclean until evening; then it will be clean. 33If any of them falls into a clay pot, everything in it will be unclean; you must break the pot. 34Any food coming into contact with water from that pot will be unclean, and any drink in such a container will be unclean.

35Anything upon which one of their carcasses falls will be unclean. If it is an oven or cooking pot, it must be smashed; it is unclean and will remain unclean for you. 36Nevertheless, a spring or cistern containing water will remain clean, but one who touches a carcass in it will be unclean.
