Dedan
Archimandrite Nikifor’s Biblical Encyclopedia
(low-lying) — the name of two localities: a) (Jer. 25:23; Ezek. 25:13) a region of Arabia Petraea, south of Edom, settled by the descendants of Dedan, son of Jokshan, son of Abraham by Keturah (Gen. 25:3); b) (Ezek. 25:13; 27:15–20; 38:13) — a country in Arabia near the Persian Gulf, which traded with Tyre in ivory, ebony, and the like, and was populated by the descendants of Dedan, son of Raamah (Gen. 10:7), of the descendants of Cush. In this country, for a long time after the fall of Tyre, there continued to exist a city called Dedan, which carried on extensive trade, in part in the very articles mentioned by the prophet Ezekiel.
The location of these places is unknown, though traces of the name Dedan are found in the present-day Dadena, one of the islands in the Persian Gulf. In the prophecy concerning Arabia (Isa. 21:13): “In the forest in Arabia shall ye lodge, O ye travelling companies of Dedanim!” In this last word, evidently, the merchant inhabitants of Dedan are meant.
