43 “You have heard that it was said, ‘Love your neighbor’ and ‘hate your enemy.’ 44 But I say to you, love your enemy and pray for those who persecute you, 45 so that you may be like your Father in heaven, since he causes the sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. 46 For if you love those who love you, what reward do you have? Even the tax collectors do the same, don’t they? 47 And if you only greet your brothers, what more do you do? Even the Gentiles do the same, don’t they? 48 So then, be perfect, as your heavenly Father is perfect.
The Gemara asks: But does the prohibition against vengeance really not relate also to matters of personal anguish suffered by someone? Wasn’t it taught in a baraita: Those who are insulted but do not insult others, who hear themselves being shamed but do not respond, who act out of love for God, and who remain happy in their suffering, about them the verse states: “They that love Him be as the sun when it goes forth in its might” (Judges 5:31). This baraita shows that one should forgive personal insults as well as wrongs in monetary matters.
