Here, 1. The angel Gabriel lets Daniel know the good service he has done to the Jewish nation (Dan 11:1): “In the first year of Darius the Mede, who destroyed Babylon and released the Jews out of that house of bondage, I stood a strength and fortress to him, that is, I was instrumental to protect him, and give him success in his ward, and, after he had conquered Babylon, to confirm him in his resolution to release the Jews,” which, it is likely, met with much opposition. Thus by the angel, and at the request of the watcher, the golden head was broken, and the axe laid to the root of the tree. Note, We must acknowledge the hand of God in the strengthening of those that are friends to the church for the service they are to do it, and confirming them in their good resolutions; herein he uses the ministry of angels more than we are aware of. And the many instances we have known of God's care of his church formerly encourage us to depend upon him in further straits and difficulties. 2. He foretels the reign of four Persian kings (Dan 11:2): Now I will tell thee the truth, that is, the true meaning of the visions of the great image, and of the four beasts, and expound in plain terms what was before represented by dark types. (1.) There shall stand up three kings in Persia, besides Darius, in whose reign this prophecy is dated, Dan 9:1. Mr. Broughton makes these three to be Cyrus, Artaxasta or Artaxerxes, called by the Greeks Cambyses, and Ahasuerus that married Esther, called Darius son of Hystaspes. To these three the Persians gave these attributes - Cyrus was a father, Cambyses a master, and Darius a hoarder up. So Herodotus. (2.) There shall be a fourth, far richer than they all, that is, Xerxes, of whose wealth the Greek authors take notice. By his strength (his vast army, consisting of 800,000 men at least) and his riches, with which he maintained and paid that vast army, he stirred up all against the realm of Greece. Xerxes's expedition against Greece is famous in history, and the shameful defeat that he met with. He who when he went out was the terror of Greece in his return was the scorn of Greece. Daniel needed not to be told what disappointment he would meet with, for he was a hinderer of the building of the temple; but soon after, about thirty years after the first return from captivity, Darius, a young king, revived the building of the temple, owning the hand of God against his predecessors for hindering it, Ezr 6:7. 3. He foretels Alexander's conquests and the partition of his kingdom, Dan 11:3. He is that mighty king that shall stand up against the kings of Persia, and he shall rule with great dominion, over many kingdoms, and with a despotic power, for he shall do according to his will, and undo likewise, which, by the law of the Medes and Persians, their kings could not. When Alexander, after he had conquered Asia, would be worshipped as a god, then this was fulfilled, that he shall do according to his will. That is God's prerogative, but was his pretension. But (Dan 11:4) his kingdom shall soon be broken, and divided into four parts, but not to his posterity, nor shall any of his successors reign according to his dominion; none of them shall have such large territories nor such an absolute power. His kingdom was plucked up for others besides those of his own family. Arideus, his brother, was made king in Macedonia; Olympias, Alexander's mother, killed him, and poisoned Alexander's two sons, Hercules and Alexander. Thus was his family rooted out by its own hands. See what decaying perishing things worldly pomp and possessions are, and the powers by which they are got. Never was the vanity of the world and its greatest things shown more evidently than in the story of Alexander. All is vanity and vexation of spirit.
