'Strongholds' in the Bible

The Lord hath swallowed up all the habitations of Jacob, and hath not pitied: He hath thrown down in his wrath the strongholds of the daughter of Judah; He hath brought them down to the ground; he hath profaned the kingdom and the princes thereof.

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 he hath multiplied in the daughter of Judah mourning and lamentation.
