Ben Sira 21:12

12 The one who is not clever cannot be taught, but there is a cleverness that increases bitterness.

Ben Sira 21:12 In-Context

10 The way of sinners is paved with smooth stones, but at its end is the pit of Hades.

11 Whoever keeps the law controls his thoughts, and the fulfillment of the fear of the Lord is wisdom.

12 The one who is not clever cannot be taught, but there is a cleverness that increases bitterness.

13 The knowledge of the wise will increase like a flood, and their counsel like a life-giving spring.

14 The mind of a fool is like a broken jar; it can hold no knowledge.
