Proverbs 25:18-20

New International Reader's Version

¹⁸ A person who is a false witness against a neighbor
    is like a club, a sword or a sharp arrow.

¹⁹ Trusting someone who is not faithful when trouble comes
    is like a broken tooth or a disabled foot.

²⁰ You may sing songs to a troubled heart.
    But that’s like taking a coat away on a cold day.
    It’s like pouring vinegar on a wound.
