Ecclesiastes 10:2

Wisdom Can Be Nullified By the Caprice of Rulers

10:2 A wise person’s good sense protects him,

but a fool’s lack of sense leaves him vulnerable.

Ecclesiastes 10:10

10:10 If an iron axhead is blunt and a workman does not sharpen its edge,

he must exert a great deal of effort;

so wisdom has the advantage of giving success.

Ecclesiastes 7:25

True Righteousness and Wisdom are Virtually Nonexistent

7:25 I tried to understand, examine, and comprehend

the role of wisdom in the scheme of things,

and to understand the stupidity of wickedness and the insanity of folly.
