Ecclesiastes 3:9-11

Amplified Bible, Classic Edition

⁹ What profit remains for the worker from his toil?

¹⁰ I have seen the painful labor and exertion and miserable business which God has given to the sons of men with which to exercise and busy themselves.

¹¹ He has made everything beautiful in its time. He also has planted eternity in men’s hearts and minds [a divinely implanted sense of a purpose working through the ages which nothing under the sun but God alone can satisfy], yet so that men cannot find out what God has done from the beginning to the end.
