Ecclesiastes 8:16-17

New American Standard Bible

¹⁶ When I ^(A)devoted my ^[a]mind to know wisdom and to see the business which has been done on the earth (even though one should ^[b](B)never sleep day or night), ¹⁷ and I saw every work of God, I concluded that ^(C)one cannot discover the work which has been done under the sun. Even though a person laboriously seeks, he will not discover; and ^(D)even if the wise person claims to know, he cannot discover.
