Dispersal among the goim – foreign nations – was how God tried to sober up the Jewish people. Heathen/Gentile nations were the bad guys who saw the cheapening of God’s name.
“Now therefore, what do I do here,” says the Lord, “seeing that my people are taken away for nothing? Those who rule over them mock,” says the Lord, “and my name continually all the day is blasphemed.
