Sirach 42:4-6

New Revised Standard Version Catholic Edition

⁴ of accuracy with scales and weights,
    and of acquiring much or little;
⁵ of profit from dealing with merchants,
    and of frequent disciplining of children,
    and of drawing blood from the back of a wicked slave.
⁶ Where there is an untrustworthy wife, a seal is a good thing;
    and where there are many hands, lock things up.
