Dumah.Dumah is probably the same as Dumatha, a city of Arabia, mentioned by Stephanus, and the modern Dumah and Dumathalgandel, on the borders of Arabia and Syria, in a rocky valley. The Edomites, says Bp. Lowth, as well as Jews, were subdued by the Babylonians. They enquire of the prophet how long their subjection is to last; he intimates that the Jews should be delivered from their captivity; not so the Edomites. "The morning cometh, and also the night."
