Sirach 21:24-26

Revised Standard Version Catholic Edition

²⁴ It is ill-mannered for a man to listen at a door,
    and a discreet man is grieved by the disgrace.
²⁵ The lips of strangers will speak of these things,^[a]
    but the words of the prudent will be weighed in the balance.
²⁶ The mind of fools is in their mouth,
    but the mouth of wise men is in^[b] their mind.
