Ben Sira 41:14

14 My children, do as I teach you and live at peace. Wisdom that is not expressed is like a treasure that has been hidden - both are useless.

Ben Sira 41:14 In-Context

12 Protect your reputation; it will outlive you and last longer than a thousand treasures of gold.
13 A good life lasts only so long, but a good reputation will last forever.
14 My children, do as I teach you and live at peace. Wisdom that is not expressed is like a treasure that has been hidden - both are useless.
15 A person who covers up his foolishness is better than one who keeps his wisdom to himself.
16 My children, listen and I will teach you the circumstances when it is proper to be ashamed. Sometimes it is entirely out of place.
