'Heaps' in the Bible

And there came a messenger, and told him, saying, They have brought the heads of the king's sons. And he said, Lay ye them in two heaps at the entering in of the gate until the morning.

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.
