Ecclesiastes 2:20-23

2:20 So I began to despair about all the fruit of my labor

for which I worked so hard on earth.

2:21 For a man may do his work with wisdom, knowledge, and skill;

however, he must hand over the fruit of his labor as an inheritance

to someone else who did not work for it.

This also is futile, and an awful injustice!

Painful Days and Restless Nights

2:22 What does a man acquire from all his labor

and from the anxiety that accompanies his toil on earth?

2:23 For all day long his work produces pain and frustration,

and even at night his mind cannot relax!

This also is futile!
