Sirach 42:6-8

Revised Standard Version

⁶ Where there is an evil wife, a seal is a good thing;
    and where there are many hands, lock things up.
⁷ Whatever you deal out, let it be by number and weight,
    and make a record of all that you give out or take in.
⁸ Do not be ashamed to instruct the stupid or foolish
    or the aged man who quarrels with the young.
Then you will be truly instructed,
    and will be approved before all men.
