Ben Sira 37:19

19 Some people may be clever enough to teach many, and yet be useless to themselves.

Ben Sira 37:19 In-Context

17 The mind is the root of all conduct;
18 it sprouts four branches, good and evil, life and death; and it is the tongue that continually rules them.
19 Some people may be clever enough to teach many, and yet be useless to themselves.
20 A skillful speaker may be hated; he will be destitute of all food,
21 for the Lord has withheld the gift of charm, since he is lacking in all wisdom.
