Proverbs 25:21 KJV

19Confidence in an unfaithful man in time of trouble is like a broken tooth, and a foot out of joint.

20As he that taketh away a garment in cold weather, and as vinegar upon nitre, so is he that singeth songs to an heavy heart.

21If thine enemy be hungry, give him bread to eat; and if he be thirsty, give him water to drink:

22For thou shalt heap coals of fire upon his head, and the LORD shall reward thee.

23The north wind driveth away rain: so doth an angry countenance a backbiting tongue.
