If your enemy is hungry, give him bread to eat; and if he is thirsty, give him water to drink
A proverb teaching not to bear a grudge against your enemy and to try to help him when he is in trouble. Helping him will lead him to self-reflection, and perhaps he will understand that reconciliation is possible with you (regarding the commandment to help even your enemy, see: Exodus 23:5).
("If your enemy is hungry, give him bread to eat; and if he is thirsty, give him water to drink" – Proverbs 25:21)
