II. He shows them the folly of making their addresses to idols as their fathers had done (v. 2): The idols have spoken vanity; the teraphim, which they courted and consulted in their distress, were so far from being able to command rain for them that they could not so much as tell them when they should have rain. They pretended to promise them rain at such a time, but it did not come. The diviners, who were the prophets of those idols, have seen a lie (their visions were all a cheat and a sham); and they have told false dreams, such as the event did not answer, which proved that they were not from God. Thus they comforted in vain those that consulted the lying oracles; all the vanities of the heathen put together could not give rain, Jer. xiv. 22. Yet this was not the worst of it; they not only got nothing by the false gods, but they lost the favour of the true God, for therefore they went their way into captivity as a flock driven into the fold, and they were troubled with one vexation after another, as scattered sheep are, because there was no shepherd, no prince to rule them, no priest to intercede for them, none to take care of them and keep them together. Those that wandered after strange gods were made to wander, into strange nations.
