Zechariah 14:12-15 MSG

12 But this is what will happen to all who fought against Jerusalem: God will visit them with a terrible plague. People's flesh will rot off their bones while they are walking around; their eyes will rot in their sockets and their tongues in their mouths; people will be dying on their feet!
13 Mass hysteria when that happens - total panic! Fellow soldiers fighting and killing each other - holy terror!
14 And then Judah will jump into the fray!
15 The plague will also hit the animals - horses, mules, camels, donkeys. Everything alive in the military camps will be hit by the plague.
