'Heaps' in the Bible

Nothing remains but to crouch among the captivesOr fall [dead] among the slain [on the battlefield].In spite of all this, God’s anger does not turn away,But His hand is still stretched out [in judgment].

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.
