Sirach 4:20-22

New Revised Standard Version, Anglicised Catholic Edition

²⁰ Watch for the opportune time, and beware of evil,
    and do not be ashamed to be yourself.
²¹ For there is a shame that leads to sin,
    and there is a shame that is glory and favour.
²² Do not show partiality, to your own harm,
    or deference, to your downfall.
