Proverbs 25:20-22

World English Bible

²⁰ As one who takes away a garment in cold weather,
    or vinegar on soda,
    so is one who sings songs to a heavy heart.
²¹ If your enemy is hungry, give him food to eat.
    If he is thirsty, give him water to drink;
²² for you will heap coals of fire on his head,
    and Yahweh will reward you.
