'Vengeance' in the Bible

You shall not seek vengeance, and you shall not harbor a grudge [against] {your fellow citizens}; and you shall love your neighbor like yourself; I [am] Yahweh.

And I will bring upon you a sword that seeks vengeance [for the] covenant, and you shall be gathered to your cities; and I will send a plague in your midst, and you shall be given into [the] hand of an enemy.
