Ecclesiastes 2:19

2:19 Who knows if he will be a wise man or a fool?

Yet he will be master over all the fruit of my labor

for which I worked so wisely on earth!

This also is futile!

Ecclesiastes 5:10

Covetousness

5:10 The one who loves money will never be satisfied with money,

he who loves wealth will never be satisfied with his income.

This also is futile.

Ecclesiastes 8:1

Human Government Demonstrates Limitations of Wisdom

8:1 Who is a wise person? Who knows the solution to a problem?

A person’s wisdom brightens his appearance, and softens his harsh countenance.
