Wisdom 1:9-11

New Catholic Bible

⁹ For the schemes of the wicked man will be investigated,
    and the sound of his words will reach the Lord
    to convict him of his transgressions,
¹⁰ because a jealous ear listens to everything,
    and no sound of grumbling remains secret.
¹¹ Therefore, beware of futile grumbling
    and restrain your tongue from calumny,^[a]
for even something said in secret has repercussions,
    and a lying mouth destroys the soul.
