Isaiah 21:11  (King James Version)
The burden of Dumah. He calleth to me out of Seir, Watchman, what of the night? Watchman, what of the night?

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."
