Ecclesiastes 1:13; Ecclesiastes 1:16-18

Ecclesiastes 1:13

13 And I set my mind to seek and explore by wisdom concerning all that has been done under heaven. It is a grievous task which God has given to the sons of men to be afflicted with.

Ecclesiastes 1:16-18

16 I said to myself, "Behold, I have magnified and increased wisdom more than all who were over Jerusalem before me; and my mind has observed a wealth of wisdom and knowledge."

17 And I set my mind to know wisdom and to know madness and folly; I realized that this also is striving after wind.

18 Because in much wisdom there is much grief, and increasing knowledge results in increasing pain.
