Ecclesiastes 2:17-19

American Standard Version

¹⁷ So I hated life, because the work that is wrought under the sun was grievous unto me; for all is vanity and a striving after wind. ¹⁸ And I hated all my labor wherein I labored under the sun, seeing that I must leave it unto the man that shall be after me. ¹⁹ And who knoweth whether he will be a wise man or a fool? yet will he have rule over all my labor wherein I have labored, and wherein I have showed myself wise under the sun. This also is vanity.
