Sirach 4:20-25 New Revised Standard Version Catholic Edition (NRSVCE)
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 favor.
22 Do not show partiality, to your own harm,
or deference, to your downfall.
23 Do not refrain from speaking at the proper moment,
and do not hide your wisdom.
24 For wisdom becomes known through speech,
and education through the words of the tongue.
25 Never speak against the truth,
but be ashamed of your ignorance.
