Sirach 23:12-15

New Revised Standard Version Updated 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.^(A)
13 Do not accustom your mouth to lewd ignorance,
    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 habit;
then you will wish that you had never been born,
    and you will curse the day of your birth.^(B)
15 Those who are accustomed to using abusive language
    will never become disciplined as long as they live.
