Esther 1:3

Made a feast unto all his princes and his servants By his servants are meant his subjects, who were called servants in the eastern countries. And it was the manner of the Roman emperors, sometimes to feast all the people of Rome, as well as the senate. The power of Persia and Media The mighty men, the chief officers of state, and commanders of all his forces; whom, by this splendid entertainment, he endeavoured to oblige, and assure to himself. What the occasion of this feast was, is variously conjectured. Some think it was begun on his birth-day; but the next words seem to inform us, that it was to show his magnificent greatness to all his subjects; for in those countries they delighted much in making great feasts, as we read afterward that Alexander, when he was there, entertained four hundred captains, or great commanders, who all sat in silver chairs, &c.
