I. That the false gods will certainly fail their worshippers when they have most need of them, v. 1, 2. Bel and Nebo were two celebrated idols of Babylon. Some make Bel to be a contraction of Baal; others rather think not, but that it was Belus, one of their first kings, who after his death was deified. As Bel was a deified prince, so (some think) Nebo was a deified prophet, for so Nebo signifies; so that Bel and Nebo were their Jupiter and their Mercury or Apollo. Barnabas and Paul passed at Lystra for Jupiter and Mercury. The names of these idols were taken into the names of their princes, Bel into Belshazzar's, Nebo into Nebuchadnezzar's and Nebuzaradan's, &c. These gods they had long worshipped, and in their revels praised them for their successes (as appears, Dan. v. 4); and they insulted over Israel as if Bel and Nebo were too hard for Jehovah and could detain them in captivity in defiance of their God. Now, that this might be no discouragement to the poor captives, God here tells them what shall become of these idols, which they threaten them with. When Cyrus takes Babylon, down go the idols. It was usual then with conquerors to destroy the gods of the places and people they conquered, and to put the gods of their own nation in the room of them, ch. xxxvii. 19. Cyrus will do so; and then Bel and Nebo, that were set up on high, and looked great, bold, and erect, shall stoop and bow down at the feet of the soldiers that plunder their temples. And because there is a great deal of gold and silver upon them, which was intended to adorn them, but serves to expose them, they carry them away with the rest of the spoil. The carriers' horses, or mules, are laden with them and their other idols, to be sent among other lumber (for so it seems they accounted them rather than treasure) into Persia. So far are they from being able to support their worshippers that they are themselves a heavy load in the wagons, and a burden to the weary beast. The idols cannot help one another (v. 2): They stoop, they bow down together. They are all alike, tottering things, and their day has come to fall. Their worshippers cannot help them: They could not deliver the burden out of the enemy's hand, but themselves (both the idols and the idolaters) have gone into captivity. Let not therefore God's people be afraid of either. When God's ark was taken prisoner by the Philistines it proved a burden, not to the beasts, but to the conquerors, who were forced to return it; but, when Bel and Nebo have gone into captivity, their worshippers may even give their good word with them: they will never recover themselves.
