Proverbs 25:20-22

New Revised Standard Version Updated Edition

²⁰ Like vinegar on a wound^[a]
    is one who sings songs to a heavy heart.
Like a moth in clothing or a worm in wood,
    sorrow gnaws at the human heart.^[b]
21 If your enemies are hungry, give them bread to eat,
    and if they are thirsty, give them water to drink,^(A)
22 for you will heap coals of fire on their heads,
    and the Lord will reward you.^(B)
