'Defenced' in the Bible

For thou hast made of a city an heap; of a defenced city a ruin: a palace of strangers to be no city; it shall never be built.

Yet the defenced city shall be desolate, and the habitation forsaken, and left like a wilderness: there shall the calf feed, and there shall he lie down, and consume the branches thereof.

Now it came to pass in the fourteenth year of king Hezekiah, that Sennacherib king of Assyria came up against all the defenced cities of Judah, and took them.

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