Ecclesiastes 1:12~18
¹²I, the Teacher, was king over Israel in Jerusalem. ¹³I devoted myself to study and to explore by wisdom all that is done under heaven. What a heavy burden God has laid on men! ¹⁴I have seen all the things that are done under the sun; all of them are meaningless, a chasing after the wind. ¹⁵What is twisted cannot be straightened; what is lacking cannot be counted. ¹⁶I thought to myself, "Look, I have grown and increased in wisdom more than anyone who has ruled over Jerusalem before me; I have experienced much of wisdom and knowledge." ¹⁷Then I applied myself to the understanding of wisdom, and also of madness and folly, but I learned that this, too, is a chasing after the wind. ¹⁸For with much wisdom comes much sorrow; the more knowledge, the more grief.
