Daniel 4:33

He was driven from men; being bereft of his understanding, as a man distracted, he fled, and betook himself to the woods; or was thrust and driven out, either by popular tumults, or conspiracy of his nobles, or by his son Evil-merodach. Some think, when he raved, he was bound with chains, and after turned off loose into the woods among beasts. And his nails like birds claws, which might easily grow in seven years to a prodigious length and deformity.
