An ancient city in the plain of Judah, southwest of Jerusalem, Ge 38:1Jos 15:35. Its king was slain by Joshua, Jos 12:15. It was one of the cities rebuilt and fortified by Rehoboam, 2Ch 11:7Mic 1:15, and was reoccupied by the Jews after the captivity, Ne 11:30.
When David withdrew from Achish, king of Gath, he retired to the "cave of Adullam," 1Sa 22:12Sa 23:13. The location of this cave, however, is uncertain. Tradition places it in the hill country, about six miles south-east of Bethlehem, the city of David; a large and fine cave, visited by many travellers. It is capable of holding thousands.
