(Hebrew Adhullam, Vulgate Odollam, but Adullam in Joshua 15:35.)
(1) A Chanaanite city, to the west of Bethlehem, at the foot of the mountains of Juda. From the hands of the Chanaanites (Genesis 38:1 ff.) it passed into the power of Juda (Joshua 12:15; 15:35), was fortified by Roboam (2 Chronicles 11:7), mentioned by the prophet Micheas (1:15), and after the exile re-peopled by Jews (Nehemiah 11:30; 2 Maccabees 12:38).
(2) The Cave of Adullam, the shelter of David and his followers (1 Samuel 22:1, 2), is situated, according to some, six miles southeast of Bethlehem, in the Wady Khareitun; but more probably near the city of Adullam.
