In this verse the Prophet expresses what he had before referred to, that God would become in such a way the avenger of the pride and cruelty of the Moabites as to punish them for their superstitions. They had descended from a pious father, for they were the posterity of Lot; but they had renounced the worship of the only true God, and had defiled themselves with the pollutions of heathens. Justly then does God declare that he would be the avenger of idolatry, while executing punishment on the pride and cruelty of the Moabites.

Now this passage, as innumerable others, clearly shews that idolatry and all profanation of divine worship, cannot finally escape punishment. God may indeed for a time connive at it, but he must necessarily at last appear as the vindicator of his own glory in punishing superstitions. But, if he spared not the Moabites, to whom the law had not, been given, and who had been corrupted through many long years, how shall they now escape unpunished, to whom God’s Word is daily propounded, and in whose ears it sounds? Let, us then remember that superstitions cannot be endured, for God will at length vindicate his own glory with regard to these abominations; for every superstition is nothing less than a profanation of God’s glory, which is thus transferred to idols and vain inventions.
