Proverbs 12:17-19

New Revised Standard Version Catholic Edition

¹⁷ Whoever speaks the truth gives honest evidence,
    but a false witness speaks deceitfully.
¹⁸ Rash words are like sword thrusts,
    but the tongue of the wise brings healing.
¹⁹ Truthful lips endure forever,
    but a lying tongue lasts only a moment.
