Or HaChaim on Deuteronomy 32:31/אור החיים על דברים ל״ב:ל״א

1 כי לא כצורנו צורם, "For our Rock is not like their Rock, etc." Moses means that the reason that one Gentile was able to put to flight a thousand Jews was not due to G'd's lack of power but to His deliberate decision to "sell out" His people. Israel's troubles are not due to the sudden prowess of the Gentile nations. Israel's source of strength, as we pointed out in connection with the debacle of the spies, is not comparable to the short-lived source of strength of the idolators. This is the mystical dimension of Proverbs 12,19: ועד ארגיעה לשון שקר. "but a lying tongue endures only briefly." We can learn from the idolatry practiced by many nations when they worshiped the god Kemosh, a national god of the Moabites. Although, according to Rabbi Saadyah Gaon, many marvellous deeds were attributed to that deity, it did not take long before people ceased to worship it. Many other deities which enjoyed a great reputation in antiquity suffered a similar fate. Our Rock, by comparison, remains at the height of His power as even the Gentiles admit, compare Maleachi, 1,11: "for My name is great among the nations." If these nations observe the downfall of Israel they too will arrive at the conclusion that their religion is true, after all. ואיבינו פלילים, "yet our enemies judge us." The word is used in the sense it is used in Exodus 21,22 ונתן בפלילים, "he shall pay it, (the damages) by order of the judges." Whereas up until then even the nations had admitted that the power of the G'd of the Jews was in a class by itself, the demise of the Jewish people will convince them that they had been wrong.
