Ecclesiastes 8:16-17

New Revised Standard Version Catholic Edition

¹⁶ When I applied my mind to know wisdom, and to see the business that is done on earth, how one’s eyes see sleep neither day nor night, ¹⁷ then I saw all the work of God, that no one can find out what is happening under the sun. However much they may toil in seeking, they will not find it out; even though those who are wise claim to know, they cannot find it out.
