'Ruinous' in the Bible

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 fenced cities into ruinous heaps.

The burden of Damascus. Behold, Damascus is taken away from being a city, and it shall be a ruinous heap.

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.
