Ecclesiastes 1:12-16

I, the Teacher, was king over Israel in Jerusalem. I applied my mind to study and to explore by wisdom all that is done under the heavens. What a heavy burden God has laid on mankind! I have seen all the things that are done under the sun; all of them are meaningless, a chasing after the wind. What is crooked cannot be straightened; what is lacking cannot be counted. I said to myself, “Look, I have increased in wisdom more than anyone who has ruled over Jerusalem before me; I have experienced much of wisdom and knowledge.”
