Sirach 23:12-14

New Revised Standard Version Catholic Edition

¹² There is a manner of speaking comparable to death;^[a]
    may it never be found in the inheritance of Jacob!
Such conduct will be far from the godly,
    and they will not wallow in sins.
¹³ Do not accustom your mouth to coarse, foul language,
    for it involves sinful speech.
¹⁴ Remember your father and mother
    when you sit among the great,
or you may forget yourself in their presence,
    and behave like a fool through bad habit;
then you will wish that you had never been born,
    and you will curse the day of your birth.
