Also the nation they serve will I judge, and afterward they will go out with great substance (Gen. 15:14)
Just as those Jews during the Egyptian and Babylonian exiles who put their faith in the nations and their kings for salvation were proven wrong, so too will those who, in our present exile, think that we must rely on the nations of the world for our continued existence and redemption. When Moshiach comes and G-d judges all the nations, the Jews will see that their faith was misplaced. At that time we will also "go out with great substance," the greatest riches of them all - the ultimate Redemption.
