Sirach 10:24-26

Revised Standard Version

²⁴ The nobleman, and the judge, and the ruler will be honored,
    but none of them is greater than the man who fears the Lord.
²⁵ Free men will be at the service of a wise servant,
    and a man of understanding will not grumble.

²⁶ Do not make a display of your wisdom when you do your work,
    nor glorify yourself at a time when you are in want.
