Deuteronomy 32:30

30.How should one chase a thousand. Of all the many tokens of God’s wrath, he selects one which was peculiarly striking; for as long as God was on their side, they had put to flight mighty armies, nor had they been supported by any multitude of forces. Now, when, though in great numbers, they are conquered by a few, this change plainly shows that they are deprived of God’s aid, especially when a thousand, who were wont before, with a little band, to rout the greatest armies, gave way before ten men. Moses, therefore, condemns the stupidity of the people, in that it does not occur to their minds that they are rejected by God, when they are so easily overcome by a few enemies, whom they far exceed in numbers. Moses, however, goes still further, and says, that they were sold and betrayed; (279) inasmuch as God, having so often found them to be unworthy of His aid, not only deserted them, but made them subject to heathen nations, and, as it were, sold them to be their slaves. This threat is often repeated by the prophets: and Isaiah, desiring to awake in them a hope of deliverance, tells them that God would redeem the people whom He had sold. (280) But, in case any should object that it was no matter of wonder, if the uncertain chance of war should confer on others the victory which often, as a profane poet says,

“Hovers between the two on doubtful wings,” (281)

Moses anticipates the objection by declaring that, unless the people should be deprived of God’s aid, they could not be otherwise than successful. A comparison is therefore instituted between the true God and false gods: as though Moses had said that, where the God of hosts presides, the issue of war can never be doubtful. Hence it follows, that God’s elect and peculiar people are exempted from the ordinary condition of nations, except in so far as it deserves to be rejected on the score of its ingratitude. He calls the unbelievers themselves to be the arbiters and witnesses of this, inasmuch as they had often experienced the formidable power of God, and knew assuredly that the God of Israel was unlike their idols. It is, then, just as if he had said, that this was conspicuous even to the blind, or were to cite as witnesses those who are blessed with no light from on high. In thus inviting unbelievers to be judges, it is not as if he supposed that they would pronounce what was true, and thoroughly understood by them, but because they must needs be convinced by experience: for, if any one had asked the heathen whether the supreme government and power of heaven and earth were in the hands of the One God of Israel, they never would have confessed that their idols were mere vanity. Still, however malignantly they might detract from God’s glory, Moses does not hesitate to boast, even themselves being judges, that God had magnificently exerted His unconquered might; although he refers rather to the experience of facts themselves, than to their feelings. Other commentators extract a different meaning, viz., that although unbelievers might be victorious, still God remained unaffected by it: neither was his arm broken, because he permitted them to afflict the apostate Israelites: (282) the former exposition, however, is the more appropriate one.
