Hauran
   cave-land, mentioned only in Ezek. 47:16, 18. It was one of the
   ancient divisions of Bashan (q.v.), and lay on the south-east of
   Gaulanitis or the Jaulan, and on the south of Lejah, extending
   from the Arnon to the Hieromax. It was the most fertile region
   in Syria, and to this day abounds in the ruins of towns, many of
   which have stone doors and massive walls. It retains its ancient
   name. It was known by the Greeks and Romans as "Auranitis."
