1 Thessalonians 5:15
See that none render evil for evil to any man; but ever follow that which is good, both among yourselves, and to all men.
Bacon said, "He that studieth revenge keepeth his own wounds green." Philip the Good, of Burgundy, had it in his power to punish one who had behaved ill to him; but he said, "It is a fine thing to have revenge in one's power, but it is a finer thing not to use it." Another king of France said of his foes, "I will weigh down the lead of their wickedness with the gold of my kindness." A minister remarked, "Some persons would have had no particular interest in my prayers, but for the injuries they did me."
(H. R. Burton.)
