Proverbs 12:17-19

Revised Standard Version Catholic Edition

¹⁷ He who speaks the truth gives honest evidence,
    but a false witness utters deceit.
¹⁸ There is one whose rash words are like sword thrusts,
    but the tongue of the wise brings healing.
¹⁹ Truthful lips endure for ever,
    but a lying tongue is but for a moment.
