Ezekiel 35:11

therefore, as I live, saith the Lord God, I will even do according to thine anger, rewarding it with the injury which it deserved, and according to thine envy which thou hast used out of thy hatred against them, for anger and envy grow out of hatred and show themselves in word and deed; and I will make myself known among them when I have judged thee, that is, by punishing Edom for his pride and the crimes of his hatred, the Lord would bear witness of Himself that he would not permit His people and their land to be attacked and devastated without taking revenge upon the enemies.
