An ancient city in the plain of Judah, southwest of Jerusalem, Genesis 38:1 Joshua 15:35 . Its king was slain by Joshua, Joshua 12:15 . It was one of the cities rebuilt and fortified by Rehoboam, 2 Chronicles 11:7 Micah 1:15 , and was reoccupied by the Jews after the captivity, Nehemiah 11:30 .
When David withdrew from Achish, king of Gath, he retired to the "cave of Adullam," 1 Samuel 22:1 2 Samuel 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.
