Ecclesiastes 2:18-23

Revised Standard Version

¹⁸ I hated all my toil in which I had toiled under the sun, seeing that I must leave it to the man who will come after me; ¹⁹ and who knows whether he will be a wise man or a fool? Yet he will be master of all for which I toiled and used my wisdom under the sun. This also is vanity. ²⁰ So I turned about and gave my heart up to despair over all the toil of my labors under the sun, ²¹ because sometimes a man who has toiled with wisdom and knowledge and skill must leave all to be enjoyed by a man who did not toil for it. This also is vanity and a great evil. ²² What has a man from all the toil and strain with which he toils beneath the sun? ²³ For all his days are full of pain, and his work is a vexation; even in the night his mind does not rest. This also is vanity.
