Daniel 4:4,5 - Joseph Benson’s Commentary on the Old and New Testaments

I Nebuchadnezzar was at rest, &c. Nebuchadnezzar, “for the extent of his dominion, and the great revenues it supplied; for his unrivalled success in war; for the magnificence and splendour of his court; and for his stupendous works and improvements at Babylon, was the greatest monarch, not only of his own times, but incomparably the greatest the world had ever seen. At a time when he was at rest in his house, and flourishing in his palace;” having lately subjected to his empire Syria, Phenicia, Judea, Egypt, and Arabia, and returned to Babylon inflated with his success and victories, and being in the meridian of his glory, and thinking of nothing but enjoying in peace the fruit of his conquests, he was unexpectedly alarmed, and thrown into trouble and distress, by a prophetic dream which he here records. Thus God's particular judgments often resemble the general one in their coming suddenly and unexpectedly, when men indulge themselves in carnal security.
