EZK 33:27

27 Say thou thus unto them, Thus saith Adonoi Hashem: As I live, surely they that are in the ruins shall fall by the cherev, and him that is in the open sadeh will I give to the wild animals to be devoured, and they that be in the metzudot [(strongholds)] and in the me'arot [(caves)] shall die of dever [(plague)].
