Ecclesiastes 2:15

2:15 So I thought to myself, “The fate of the fool will happen even to me!

Then what did I gain by becoming so excessively wise?”

So I lamented to myself,

“The benefits of wisdom are ultimately meaningless!”

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!
