“If your enemy is hungry to feed him, and if is thirsty give him something to drink.” (Proverbs 20:21 later quoted in Romans 12:20).  The book of Leviticus (19:18) said, “Love your neighbor,” and many assumed that meant, “Hate your enemy.”  The above proverb was an attempt to get them to think in another direction.  Paul sees the reason behind this command to give food and water to your enemy and adds his commentary: “Do not be overcome by evil, but overcome evil with good” Romans 12:21.  The evil actions of enemies can only be overcome if we refuse retaliation and give good in return for evil.  That is a much better way to live than to live with anger, resentment and hatred.  Follow this way of Christ, so well stated in an OT proverb.
