Isaías 21:13-15

13-15. Burden upon Arabia On critical grounds, both Ewald and Delitzsch make it doubtful that Arabia, as a whole, is meant, but rather think that the oracle relates to the sandy desert, the Arabah, the region over which the ancient caravan trade was carried. Their opinion is not simply plausible, it is reasonable. It is still Arabia, though a specific part. The caravans are called Dedanim, a mixture of Cushites and Ishmaelites. Their roads or camel routes to and from Tyre, and probably Gaza, are invaded by a foreign force, possibly the Assyrian, in its foraging parties, as the army passes toward Egypt or toward Tyre; and the caravans are dispersed from their accustomed track of travel far out into inhospitable deserts.

Forest Forests, properly so-called, do not exist in Arabia. In wide and moist wadies thickets grow, and in these the caravans could conceal themselves when pursued.
