Joab: 2 Samuel 11:25; 1 Chronicles 20:1
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 se 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.
