Proverbs 25:19-21

New Living Translation

¹⁹ Putting confidence in an unreliable person in times of trouble
    is like chewing with a broken tooth or walking on a lame foot.

²⁰ Singing cheerful songs to a person with a heavy heart
    is like taking someone’s coat in cold weather
    or pouring vinegar in a wound.^[a]

²¹ If your enemies are hungry, give them food to eat.
    If they are thirsty, give them water to drink.
