'Fortified Cities' in the Bible

On that day, {its fortified cities} will be like the {abandonment of the wooded place and the summit}, which they deserted because of the children of Israel; and there will be desolation.

And this happened: In {the fourteenth year} of King Hezekiah, Sennacherib king of Assyria went up against all the fortified cities of Judah, and he captured them.

Have you not heard from {a long time ago}? I have made it from days of primeval time, and I formed it. Now I have brought it [about], and it is for fortified cities to collapse into heaps of destroyed stones.
