Proverbs 13:2-4

Revised Standard Version

² From the fruit of his mouth a good man eats good,
    but the desire of the treacherous is for violence.
³ He who guards his mouth preserves his life;
    he who opens wide his lips comes to ruin.
⁴ The soul of the sluggard craves, and gets nothing,
    while the soul of the diligent is richly supplied.
