A king of kings; he means Nebuchadnezzar in person, together with his successors, Evil-merodach and Belshazzar. The prophet would not mind the king of any thing past, nor of any other governments but those with whom his church were then and to be concerned for the future, till the coming of the Messiah, by whose coming they should support and comfort themselves against all their sufferings by oppressors; and also God would have the prophet mind Nebuchadnezzar of the stone cut out of the mountain without hands, growing and breaking in pieces all earthly power. The God of heaven hath given thee a kingdom; it came not to thee by thy ancestors, or by fortune, or by thy valour, but the great God of heaven hath the bestowing of those, and giveth them to whomsoever he will. Power, and strength, and glory; authority; victorious armies, with great prosperity.
