Rom Romans, chapter Epistle to the Romans, chapter 12
not avenging yourselves, beloved, but give place to the wrath, for it has been written: “Vengeance [is] Mine, I will repay again, says the LORD”; if, then, your enemy hungers, feed him; if he thirsts, give him drink; for doing this, you will heap coals of fire on his head. Do not be overcome by the evil, but overcome, in the good, the evil.
