A city in southern Judea (Josh. xv. 58, I Chron. ii. 45; Neh. iii. 16) which was fortified by Rehoboam, (II Chron. xi. 7). It was a strongly walled place, situated on the eastern boundary-line of Judea. The town was repeatedly besieged during the time of the Maccabees (I Macc. iv. 28 et seq., vi. 50, ix. 52, x. 14, xi. 65). Its situation is indicated by the ruins near a hill of Bêt-sur, or Burj-sur.
