Proverbs 25:18-22

A man that beareth false witness against his neighbor Is a maul, and a sword, and a sharp arrow. Confidence in an unfaithful man in time of trouble Is like a broken tooth, and a foot out of joint. As one that taketh off a garment in cold weather, and as vinegar upon soda, So is he that singeth songs to a heavy heart. If thine enemy be hungry, give him bread to eat; And if he be thirsty, give him water to drink: For thou wilt heap coals of fire upon his head, And Jehovah will reward thee.
