Ecclesiastes 2:20-22

21st Century King James Version

²⁰ Therefore I went about to cause my heart to despair of all the labor which I had done under the sun.

²¹ For a man may labor in wisdom and in knowledge and in equity; yet to a man who hath not labored therein shall he leave it for his portion. This also is vanity and a great evil.

²² For what hath man for all his labor and for the vexation of his heart wherewith he hath labored under the sun?
