(1.) A city in Moab (Numbers 21:30); called also Dibon-gad (33:45), because it was built by Gad and Dimon (Isaiah 15:9). It has been identified with the modern Diban, about 3 miles north of the Arnon and 12 miles east of the Dead Sea. (see Moabite Stone.)
(2.) A city of the tribe of Judah, inhabited after the Captivity (Nehemiah 11:25); called also Dimonah (Joshua 15:22). It is probably the modern ed-Dheib.
