The language here is remarkable:  "Thy heaven;" that part of
   the atmosphere which was over Judea, instead of being
   replenished with aqueous vapours, should become, with respect
   to moisture, like brass:  and consequently their land would
   become as hard as iron, and wholly incapable of cultivation;
   while the clouds might give showers in abundance, and the
   earth be moist and fruitful in other regions.
