Ecclesiastes 1:14
13. And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven: this sore travail hath God given to the sons of man to be exercised therewith.14. I have seen all the works that are done under the sun; and, behold, all is vanity and vexation of spirit.15. That which is crooked cannot be made straight: and that which is wanting cannot be numbered.
