 * Rabbah.
   Rabbah, or Rabbath-Ammon, also called Philadelphia, from
   Ptolemy Philadelphus, king of Egypt, was situated east of
   Jordan, and, according to Eusebius, ten miles east from Jazer.
   It is sometimes mentioned as belonging to Arabia, sometimes to
   Coelo-Syria; and was one of the cities of the Decapolis east
   of Jordan.  Josephus extends the region of Perea as far as
   Philadelphia.  It is now, says Burckhardt, called Amman,
   distant about 19; miles to the S. E. by E. of Szalt, and lies
   along the banks of a river called Moiet Amman, which has its
   source in a pond, at a few hundred paces from the
   south-western end of the town, and empties itself in the
   Zerka, or Jabbok, about four hours to the northward.  This
   river runs in a valley bordered on both sides by barren hills
   of flint, which advance on the south side close to the edge of
   the stream.  The edifices which still remain, though in a
   decaying state, from being built of a calcareous stone of
   moderate hardness, sufficiently attest the former greatness
   and splendour of this metropolis of the children of Ammon.
