Sirach 21:12-14

New Revised Standard Version Updated Edition

¹² Those who are not clever cannot be taught,
    but there is a cleverness that increases bitterness.^(A)
13 The knowledge of the wise will increase like a flood
    and their counsel like a life-giving spring.^(B)
14 The mind^[a] of a fool is like a broken jar;
    it can hold no knowledge.^(C)
