Proverbs 25:21-23

²¹If thine enemy hungereth, feed thou him; if he thirsteth, give thou him water to drink;

²²for thou shalt gather together coals on his head; and the Lord shall yield to thee. (for thou shalt gather together coals upon his head; and the Lord shall reward thee.)

²³The north wind scattereth abroad rains; and a sorrowful face destroyeth a tongue backbiting. (Like the north wind scattereth rains abroad; so an angry look destroyeth a backbiting tongue.)
