Daniel 5:7 - Joseph Benson’s Commentary on the Old and New Testaments

The king cried aloud Manifesting at once great fear and great impatience; to bring in the astrologers, &c. In this he imitated Nebuchadnezzar his grandfather: it seems indeed to have been the general practice of these heathen kings, in all unexpected emergencies, to apply to these their wise men for help. But the ill success of Nebuchadnezzar, in such applications, might have taught Belshazzar a better lesson. The king said, Whosoever shall read this writing, &c. To engage these wise men to exert the utmost of their skill in this matter, he promises that whosoever would give him a satisfactory account of this writing should be dignified with the highest honours of the court; and be the third ruler in the kingdom “Grotius considers the king as the first, the king's son as the second, and the interpreter of the vision to be the third. Or it may mean, that there should be a triumvirate appointed to govern the kingdom, as was the case in the beginning of the reign of Darius, and the interpreter should be one of these. Mr. Bruce (vol. 4. p. 32) speaks of a person who was suddenly advanced to a command, the third in the kingdom of Abyssinia for rank, power, and riches; and that, at his public investiture, he had a circle of gold put upon his head, was clothed with a white and blue mantle, and made the king's lieutenant-general in the provinces allotted to him.” Wintle.
