'Strongholds' in the Bible

Kerioth will be taken, and the strongholds will be conquered, and the hearts of the warriors of Moab will be on that day like [the] heart of a woman [who] is in labor.

The warriors of Babylon have ceased to fight, they remain in the strongholds, their power has dried up, they have become as women. Her dwelling places are set on fire, her bars are broken.
