'Strongholds' in the Bible

The Lord swallowed up without pity all of Jacob's habitations. In his wrath he tore down the strongholds of fair Judah. He cast to the ground in dishonor both her kingdom and its rulers.

The Lord is become as an enemy: he hath swallowed up Israel; he hath swallowed up all her palaces; he hath destroyed his strongholds, and hath multiplied in the daughter of Judah mourning and lamentation.
