Proverbs 25:20-22

Revised Standard Version

²⁰ He who sings songs to a heavy heart
    is like one who takes off a garment on a cold day,
    and like vinegar on a wound.^[a]
21 If your enemy is hungry, give him bread to eat;
    and if he is thirsty, give him water to drink;
²² for you will heap coals of fire on his head,
    and the Lord will reward you.
