Sirach 6:19-21

New Revised Standard Version, Anglicised Catholic Edition

¹⁹ Come to her like one who ploughs and sows,
    and wait for her good harvest.
For when you cultivate her you will toil but little,
    and soon you will eat of her produce.
²⁰ She seems very harsh to the undisciplined;
    fools cannot remain with her.
²¹ She will be like a heavy stone to test them,
    and they will not delay in casting her aside.
