 Medeba
    waters of quiet, an ancient Moabite town (Num. 21:30). It was
    assigned to the tribe of Reuben (Josh. 13:16). Here was fought
    the great battle in which Joab defeated the Ammonites and their
    allies (1 Chr. 19:7-15; comp. 2 Sam. 10:6-14). In the time of
    Isaiah (15:2) the Moabites regained possession of it from the
    Ammonites. (See HANUN.)
      The ruins of this important city, now Madeba or Madiyabah, are
    seen about 8 miles south-west of Heshbon, and 14 east of the
    Dead Sea. Among these are the ruins of what must have been a
    large temple, and of three cisterns of considerable extent,
    which are now dry. These cisterns may have originated the name
    Medeba, "waters of quiet." (See OMRI.)
