Hashem warned us: Don’t invade the land of Eisav or Moav, it’s theirs and I gave it to them! Look how the Torah teaches us to respect the rights of Goyim! And of low-life people, like Eisav and the descendants of Lot. You may be the holiest kind of Jew; but you still have no right to do an injustice to these nations.
How much more do we have to respect the rights of ע ִםִי ִלא ִר ִש ִ the Yidden and ourselves!
