Ecclesiastes 2:20-22

Darby Translation

²⁰ Then I went about to cause my heart to despair of all the labour wherewith I had laboured under the sun.

²¹ For there is a man whose labour hath been with wisdom, and with knowledge, and with skill, and who leaveth it to a man that hath not laboured therein, to be his portion. This also is vanity and a great evil.

²² For what will man have of all his labour and of the striving of his heart, wherewith he hath wearied himself under the sun?
