Ecclesiastes 1:12-14 ESV
I the Preacher have been king over Israel in Jerusalem. And I applied my heart to seek and to search out by wisdom all that is done under heaven. It is an unhappy business that God has given to the children of man to be busy with. I have seen everything that is done under the sun, and behold, all is vanity and a striving after wind.
