Isaiah 21:13 The burden upon Arabia. In the forest in Arabia shall ye lodge, O ye travelling companies of Dedanim.

Dedanim was the tribe that descended from Dedan, son of Jokshan, and grandson of Abraham and Keturah (Genesis 25:3). Another Dedan is mentioned in Genesis 10:7. This Dedan was a grandson of Cush. Dedan means in Hebrew "low country" and probably referred to southern Arabia. Strong's Number = 01719. These tribes followed the caravan routes, engaging in trade throughout Mecca. According to the Bible, these groups lived in the forest in Arabia. Dedan has been identified in Cuneiform inscriptions as Al-Ula, which lies some 70 miles south-west of modern Taima in Saudi Arabia.
