Ecclesiastes 7:7

Human Wisdom Overturned by Adversity

7:7 Surely oppression can turn a wise person into a fool;

likewise, a bribe corrupts the heart.

Ecclesiastes 7:16

7:16 So do not be excessively righteous or excessively wise;

otherwise you might be disappointed.

Ecclesiastes 7:19

Wisdom Needed Because No One is Truly Righteous

7:19 Wisdom gives a wise person more protection

than ten rulers in a city.
