If one of them falls into a clay pot, everything in it will be unclean, and you must break the pot. (NIV)
And every earthen vessel into which any of these [creeping things] falls, whatever may be in it shall be unclean, and you shall break the vessel. (AMP)
And every earthen vessel, whereinto any of them falleth, whatsoever is in it shall be unclean; and ye shall break it. (KJV)
