Ben Sira 20:30

30 Wisdom that is not expressed is like a treasure that has been hidden - both are useless.

Ben Sira 20:30 In-Context

28 They will excuse your errors if they like you, so cultivate the soil and reap the harvest!

29 Gifts and bribes make even the wise blind to the truth, and prevent them from being honest in their criticism.

30 Wisdom that is not expressed is like a treasure that has been hidden - both are useless.

31 But a person who covers up his foolishness is better than one who keeps his wisdom to himself.
