Proverbs 25:18-22

Like a club and a sword and a sharp arrow Is a man who bears false witness against his neighbor. Like a bad tooth and an unsteady foot Is confidence in a faithless man in time of trouble. Like one who takes off a garment on a cold day, or like vinegar on soda, Is he who sings songs to a troubled heart. If your enemy is hungry, give him food to eat; And if he is thirsty, give him water to drink; For you will heap burning coals on his head, And the LORD will reward you.
