Ecclesiastes 2:19-21

Amplified Bible, Classic Edition

¹⁹ And who knows whether he will be a wise man or a fool? Yet he will have dominion over all my labor in which I have toiled and in which I have shown myself wise under the sun. This is also vanity (emptiness, falsity, and futility)!

²⁰ So I turned around and gave my heart up to despair over all the labor of my efforts under the sun.

²¹ For here is a man whose labor is with wisdom and knowledge and skill; yet to a man who has not toiled for it he must leave it all as his portion. This also is vanity (emptiness, falsity, and futility) and a great evil!
