Proverbs 25:18-20

Evangelical Heritage Version

¹⁸ A person who gives false testimony against his neighbor
    is a club, a sword, and a sharp arrow.
¹⁹ Confidence in an unfaithful person during a time of crisis
    is like a broken tooth or a lame foot.
²⁰ Singing songs to a despondent heart
    is like taking off a coat on a cold day
    or like vinegar on baking soda.
