'Fortified Cities' in the Bible

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

Hast thou not heard long ago that I have done it? And that from ancient days I formed it? Now have I brought it to pass, that thou shouldest lay waste fortified cities into ruinous heaps.
