Heaps, viz. of stones and rubbish. A den of dragons; noting a desolate place, not any longer fit for fine habitation of mankind, as the next words do speak; but for hideous beasts; as they had made use of the temple for a den of thieves, Jeremiah 7:11. The same also he afterwards threatens on Babylon herself, Jeremiah 51:37.
