Leviticus 11:33-35

³³Soothly a vessel of earth, in which anything of these falleth within, shall be defouled, and therefore it shall be broken.

³⁴Each meat, that ye shall eat, shall be unclean, if water of such a vessel is poured out thereon; and each flowing thing, that is drunken of such a vessel, shall be unclean;

³⁵and whatever thing of such dead bodies by themselves shall fall upon, it shall be unclean, whether furnaces, or kettles standing upon three feet, they shall be destroyed, and shall be unclean.
