Albert Barnes Commentary Nahum 2:11

"Where is the den of the lions, and the feeding-place of the young lions, where the lion [and] the lioness walked, the lion`s whelp, and none made them afraid?" — Nahum 2:11 (ASV)

Where is the dwelling of the lions, and the feeding place of the young lions? Great indeed must be the desolation that would call forth the wonder of the prophet of God. He asks, “Where is it?” For so utterly was Nineveh to be effaced that its place would scarcely be known, and now is known only by the ruins that have been buried and are now dug up. The messengers of her king had asked, “Where are the gods of Hamath and of Arpad? of Sepharvaim, Hena, and Ivah?” (2 Kings 18:34). And now it is asked of her, “Where is Nineveh?” It had destroyed utterly all lands, and now itself is utterly destroyed.

The lion dwelt, fed, and walked there, up and down, at will. All was spacious and secure. He terrified all, and none terrified him. He tore, strangled, and, as he willed, laid up booty in store. But when he had filled it to the full, he also filled up the measure of his iniquities, and his sentence came from God. Nineveh had set at naught all human power and destroyed it; now, therefore, God appears in His own Person.
