I. God will let the heathen know the meaning of his people's troubles, and rectify the mistake of those concerning them who took occasion from the troubles of Israel to reproach the God of Israel, as unable to protect them and untrue to his covenant with them. When God, upon their reformation and return to him, turned again their captivity, and brought them back to their own land, and, upon their perseverance in their reformation, wrought such great salvations for them as that from the attempts of Gog upon them, then it would be made to appear, even to the heathen that would but consider and compare things, that there was no ground at all for their reflection, that Israel went into captivity, not because God could not protect them, but because they had by sin forfeited his favour and thrown themselves out of his protection (v. 23, 24): The heathen shall know that the house of Israel went into captivity for their iniquity, that iniquity which they learned from the heathen their neighbours, because they trespassed against God. That was the true reason why God hid his face from them and gave them into the hand of their enemies. It was according to their uncleanness and according to their transgressions. Now the evincing of this will not only silence their reflections on God, but will redound greatly to his honour; when the troubles of God's people are over, and we see the end of them, we shall better understand them than we did at first. And it will appear much for the glory of God when the world is made to know, 1. That God punishes sin even in his own people, because he hates it most in those that are nearest and dearest to him, Amos iii. 2. It is the praise of justice to be impartial. 2. That, when God gives up his people for a prey, it is to correct them and reform them, not to gratify their enemies, Isa. x. 7; xlii. 24. Let not them therefore exalt themselves. 3. That no sooner do God's people humble themselves under the rod than he returns in mercy to them.
