Attempts to locate the tribe named for and descended from Dumah have produced multiple possible identifications.[1] A Dumah (Deir ad-Duma) in the vicinity of Hebron which is mentioned in Joshua 15:52 is one possibility. However, according to Geoffrey Bromiley, the oracle concerning Dumah in Isaiah 21:11-12 seems better suited to a place in Arabia, suggesting the site of Dumat al-Jandal as a more likely contender. Known today as Al-Jawf, in ancient times it is mentioned in inscriptions of the Assyrian monarchs as Adummatu and is described as "a fortress of Arabia", "situated in the desert", that was destroyed by Sennacherib's forces.[1]
