Ecclesiastes 2:19-21

Darby Translation

¹⁹ And who knoweth whether he will be a wise [man] or a fool? yet shall he have rule over all my labour at which I have laboured, and wherein I have been wise under the sun. This also is vanity.

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.
