Proverbs 12:18-20

New Catholic Bible

¹⁸ Thoughtless words wound like a sword thrust,
    but the tongue of the wise produces healing.
¹⁹ Truthful speech endures forever,
    but deceitful lies last only for a moment.^[a]
20 Deceit is in the heart of those who plot evil,
    but those who counsel peace have joy.
