Mishle 25:21-23

Orthodox Jewish Bible

²¹ If thine enemy be hungry, give him lechem to eat, and if he be thirsty, give him mayim to drink;

²² For so shalt thou heap hot coals upon his rosh, and Hashem shall reward thee.

²³ The ruach tzafon (north wind) brings forth geshem; so doth a lashon seter (backbiting tongue) bring an angry countenance.
