'Strongholds' in the Bible

"Come down from glory, and sit on parched ground, O woman who lives in Dibon, for the destroyer of Moab will come up against you to destroy you. He will destroy your strongholds.

The towns will be captured and the strongholds seized. On that day the hearts of the warriors of Moab will be like the heart of a woman in labor.

"I'll kindle a fire in the wall of Damascus, and it will devour the strongholds of Ben-hadad."

The warriors of Babylon have stopped fighting. They stay in their strongholds; their strength is dried up; they have become like women. Her buildings are set on fire; the bars of her gates are broken.
