19. Do not take your own revenge, beloved, but give opportunity for G-d's Charon Af (burning wrath), for it is written, LI NAKAM V'SHILEM ("Vengeance is mine and recompense, repayment-- I am He who will repay, says Hashem" DEVARIM 32:35).
20. "But if your enemy is hungry, feed him; if he is thirsty, give him drink; for in so doing you will heap coals of fire on his head" [MISHLE 25:21-22].
21. Do not be overcome by what is ra'a, but overcome haRah with haTov.
