John Gill Commentary Jeremiah 48:41

"Kerioth is taken, and the strongholds are seized, and the heart of the mighty men of Moab at that day shall be as the heart of a woman in her pangs." — Jeremiah 48:41 (ASV)

Kerioth is taken The name of a city in Moab, as in (Jeremiah 48:24); so Jarchi, and others; but Kimchi and Abarbinel observe, that it may be taken for an appellative, and be rendered "the cities"; everyone of the cities of Moab, which were as easily and quickly taken as one city; these may intend the cities in the plain, as the strong holds those in high places:

and the strong holds are surprised; everyone of them; so that there was not a city, or a fortified place, but what came into the enemies' hands:

and the mighty men's hearts in Moab at that day shall be as the heart
of a woman in her pangs; even the hearts of the soldiers, and the most courageous generals, shall sink within them; and they be not only as timorous as women in common, but as low spirited as a woman when she finds her pains are coming upon her, and the time of her delivery is at hand.
