Ecclesiastes 1:12-15

12I, the Preacher, was king over Israel in Jerusalem.

13And I set my heart to seek and search out by wisdom concerning all that is done under heaven; this burdensome task God has given to the sons of man, by which they may be exercised.

14I have seen all the works that are done under the sun; and indeed, all is vanity and grasping for the wind.

15What is crooked cannot be made straight, And what is lacking cannot be numbered.
