When Israel addicted themselves to an immoral life at shittim, the nations of the world rejoiced greatly, for they knew that God had distinguished Israel before all other nations, and had given them the Torah, only because their life had been moral. "Now," said they, "the crown has been taken from Israel's head, their pride is departed, for now they are no better then we." God, however, raised up Israel from their fall by sending the plague upon the sinners at Shittim, and thus purified Israel from them, so that they could again, as of yore, be proud of their family purity, through which they had been distinguished from all other nations.
