Sirach 23:14-16

New Revised Standard Version Catholic Edition

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.
¹⁵ Those who are accustomed to using abusive language
    will never become disciplined as long as they live.

¹⁶ Two kinds of individuals multiply sins,
    and a third incurs wrath.
Hot passion that blazes like a fire
    will not be quenched until it burns itself out;
one who commits fornication with his near of kin
    will never cease until the fire burns him up.
