Sirach 42:5-7

New Revised Standard Version Catholic Edition

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.
⁷ When you make a deposit, be sure it is counted and weighed,
    and when you give or receive, put it all in writing.
