Sirach 10:26-28

Revised Standard Version Catholic Edition

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.
²⁷ Better is a man who works and has an abundance of everything,
    than one who goes about boasting, but lacks bread.
²⁸ My son, glorify yourself with humility,
    and ascribe to yourself honor according to your worth.
