Matthew Poole and continuators on Isaiah 21:13

13 The burden upon Arabia. In the forest in Arabia shall ye lodg, O ye travelling companies of Dedanim .

Not, as you used to do, in the Houses or Tents of the Arabians: Whereby he implies, That that Populous Country should be turned into a desolate Wilderness.

In those Parts Travellers then did, and still do go together in Companies. See Gen. 37. 25, 28. Iob 6. 19.

Or, Dedamites; of whom see on Gen. 25. 3. Ier. 25. 23, 24. & 49. 7, 8. These were Merchants, and used to Trade with Tyre, Ezek. 27. 20. & 38. 13. and their Way lay thorow the same Parts of Arabia.
