48:1-13. The Chaldeans are to destroy the Moabites. We should be thankful that we are required to seek the salvation of men's lives, and the salvation of their souls, not to shed their blood; but we shall be the more without excuse if we do this pleasant work deceitfully. The cities shall be laid in ruins, and the country shall be wasted. There will be great sorrow. There will be great hurry. If any could give wings to sinners, still they could not fly out of the reach of Divine indignation. There are many who persist in unrepented iniquity, yet long enjoy outward prosperity. They had been long corrupt and unreformed, secure and sensual in prosperity. They have no changes of their peace and prosperity, therefore their hearts and lives are unchanged, Ps 55:19.

2. no more praise—(Isa 16:14).

in Heshbon—The foe having taken Heshbon, the chief city of Moab (Jer 48:45), in it devise evil against Moab ("it") saying, Come, &c. Heshbon was midway between the rivers Arnon and Jabbok; it was the residence of Sihon, king of the Amorites, and afterwards a Levitical city in Gad (Nu 21:26). There is a play on words in the Hebrew, "Heshbon, Hashbu." Heshbon means a place of devising or counsel. The city, heretofore called the seat of counsel, shall find other counsellors, namely, those who devise its destruction.

thou shall be cut down … Madmen—rather, by a play on words on the meaning of madmen ("silence"), Thou shalt be brought to silence, so as well to deserve thy name (Isa 15:1). Thou shalt not dare to utter a sound.
