Vengeance is mine, I will repay. Does it seem to you that I am depriving you of an activity that would give you great satisfaction? You may long to settle scores with those who have wronged you, and may feel that you are justified in doing so.
It may be frustrating for you to turn away. Do you think I ask this of you out of a misplaced sense of mercy for those who have offended you? Have you ever desired revenge and yet been able to see how it would harm you to pursue it? This is true whether you are aware of it or not. So my commandment to you is not out of mercy for your enemies. It is out of mercy for you.
