We have stated why the Prophet describes so fully the ruin of the Moabites, and dwells so long on a subject in no way obscure; it was not indeed enough merely to teach and to show what was useful to be known, but it was also necessary to add goads, that the Jews might attend to these prophecies; nay, it was necessary to drive as it were with a hammer into their minds what would have been otherwise incredible; for they deemed it a fable that the Moabites could thus be broken, laid waste, and reduced to nothing. The Prophet then would have labored in vain, or spoken ineffectually, had he described in simple and plain words what we here read. But he added vehemence to his words, as though he would drive in his words with a hammer and fasten them in the minds of the people. He then says, that Moab was ashamed, because he was smitten And then he turns again to address their neighbors, Howl, cry, and declare in Aroer: but the Prophet ironically exhorted others to howl and cry; for, as we have said, it was not his purpose to show that they deserved pity who had been the most cruel enemies to God's Church, but to show that God's vengeance would be so dreadful as to call forth cryings and howlings through the whole neighborhood. And then he adds, Declare it in Aroer; and afterwards he names many cities; as though he had said, that no corner of the land would be free from fear and anxiety, because the enemies, after having made an inroad into one part, would turn to another, so as to make no end of ravaging, until they had destroyed the whole country and all the people. Of these cities and of their situation there is no need of saying much, for it would be a useless labor. For in the last place, the Prophet sufficiently shews that what he had in view was what I have stated; for he says, on all the cities of Moab, remote as well as near: he intimates that no part of the land would be exempted from destruction; for the enemies having begun to attack it, would not cease until they had gone through every part, and desolation had spread everywhere, as though the whole country had been burnt with fire. It follows, --

Or, "Moab is ashamed, because she (Dibon) is broken" by her fortifications being battered down.

Tell ye it in Arnon - Apprize the inhabitants there that the territories of Moab are invaded, and the country about to be destroyed, that they may provide for their own safety.

(m) Moab is confounded; for it is broken down: wail and cry; tell ye it in Arnon, that Moab is laid waste,
(m) Thus they who flee will answer.

Moab is confounded, for it is broken down,.... This is the answer returned, by those that had escaped and were fleeing, to those who inquired of them; who report that the whole country of Moab was in the utmost confusion and consternation; not being able to stand before the enemy, who broke down and destroyed all that was in his way: and therefore calls upon them to
howl and cry; because of the general ruin at the nation, and who must expect themselves to share the same fate; and therefore should prepare themselves and their neighbours for it, as follows:
tell ye it in Arnon, that Moab is spoiled; the country of Arnon, so called from a river of that name, on the banks of which Aroer was situated; the inhabitants of which are desired to spread it all over that part of the country, that Moab was utterly ruined by the Chaldean army; the particulars of which follow:

Answer of the fleeing Moabites to the Ammonite inquirers (Jeremiah 48:19; Isaiah 16:2). He enumerates the Moabite cities at length, as it seemed so incredible that all should be so utterly ruined. Many of them were assigned to the Levites, while Israel stood.
in Arnon--the north boundary between Moab and Ammon (Jeremiah 48:19; Numbers 21:13).

Arnon - Arnon was the name of a river; it was the border of Moab: probably the adjacent country or city might take its name from the river.
