Daniel 3:13 - Joseph Benson’s Commentary on the Old and New Testaments

Then Nebuchadnezzar in his rage, &c. How little was it to the honour of this mighty prince that he had rule over so many nations, when, at the same time, he had no rule over his own spirit! How unfit was he to rule reasonable men, who would not himself be ruled by reason! Surely it did not need to surprise him to hear that these three men did not now serve his gods, for he knew very well they never had done it, and that their religion, to which they had always adhered, forbade them to do it. Nor had he any reason to think they acted thus in contempt of his authority, since they had in all instances showed themselves respectful and dutiful to him as their prince.
