Proverbs 25:18-22

A man who bears false witness against his neighbor Is like a club, a sword, and a sharp arrow. Confidence in an unfaithful man in time of trouble Is like a bad tooth and a foot out of joint. Like one who takes away a garment in cold weather, And like vinegar on soda, Is one who sings songs to a heavy heart. If your enemy is hungry, give him bread to eat; And if he is thirsty, give him water to drink; For so you will heap coals of fire on his head, And the LORD will reward you.
