'Fortified Cities' in the Bible

"Why are you crying, sir?" Hazael asked. "Because I know the evil that you're about to bring on the Israelis," he replied. "You'll burn down their fortified cities, execute their young men with swords, dash to pieces their little ones, and you'll tear open their pregnant women!"

The Israelis practiced secret things that were not right, offending the LORD their God. In addition, they built high places for use by all their towns, watchtowers, and fortified cities.

Now in the fourteenth year of king Hezekiah did Sennacherib king of Assyria come up against all the fortified cities of Judah, and took them.

Hast thou not heard how I have done it long ago, and formed it of ancient times? now have I brought it to pass, that it should be thine to lay waste fortified cities into ruinous heaps.
