21:11,12 God's prophets and ministers are as watchmen in the city in a time of peace, to see that all is safe. As watchmen in the camp in time of war, to warn of the motions of the enemy. After a long sleep in sin and security, it is time to rise, to awake out of sleep. We have a great deal of work to do, a long journey to go; it is time to be stirring. After a long dark night is there any hope of the day dawning? What tidings of the night? What happens to-night? We must never be secure. But many make curious inquiries of the watchmen. They would willingly have nice questions solved, or difficult prophecies interpreted; but they do not seek into the state of their own souls, about the way of salvation, and the path of duty. The watchman answers by way of prophecy. There comes first a morning of light, and peace, and opportunity; but afterward comes a night of trouble and calamity. If there be a morning of youth and health, there will come a night of sickness and old age; if a morning of prosperity in the family, in the public, yet we must look for changes. It is our wisdom to improve the present morning, in preparation for the night that is coming after it. Inquire, return, come. We are urged to do it quickly, for there is no time to trifle. Those that return and come to God, will find they have a great deal of work to do, and but little time to do it in.

Isa 21:11, 12. A Prophecy to the Idumeans Who Taunted the Afflicted Jews in the Babylonish Captivity.

One out of Seir asks, What of the night? Is there a hope of the dawn of deliverance? Isaiah replies, The morning is beginning to dawn (to us); but night is also coming (to you). Compare Ps 137:7. The Hebrew captives would be delivered, and taunting Edom punished. If the Idumean wish to ask again, he may do so; if he wishes an answer of peace for his country, then let him "return (repent), come" [Barnes].

11. Dumah—a tribe and region of Ishmael in Arabia (Ge 25:14; 1Ch 1:30); now called Dumah the Stony, situated on the confines of Arabia and the Syrian desert; a part put for the whole of Edom. Vitringa thinks "Dumah," Hebrew, "silence," is here used for Idumea, to imply that it was soon to be reduced to silence or destruction.

Seir—the principal mountain in Idumea, south of the Dead Sea, in Arabia-Petræa. "He calleth" ought to be rather, "There is a call from Seir."

to me—Isaiah. So the heathen Balak and Ahaziah received oracles from a Hebrew prophet.

Watchman—the prophet (Isa 62:6; Jer 6:17), so called, because, like a watchman on the lookout from a tower, he announces future events which he sees in prophetic vision (Hab 2:1, 2).

what of the night—What tidings have you to give as to the state of the night? Rather, "What remains of the night?" How much of it is past? [Maurer]. "Night" means calamity (Job 35:10; Mic 3:6), which, then, in the wars between Egypt and Assyria, pressed sore on Edom; or on Judah (if, as Barnes thinks, the question is asked in mockery of the suffering Jews in Babylon). The repetition of the question marks, in the former view, the anxiety of the Idumeans.
