Ecclesiastes 1:12-18 English Standard Version (ESV)
The Vanity of Wisdom
12 I the Preacher have been king over Israel in Jerusalem. 13 And I applied my heart[a] 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. 14 I have seen everything that is done under the sun, and behold, all is vanity[b] and a striving after wind.[c]
15 What is crooked cannot be made straight,
16 I said in my heart, “I have acquired great wisdom, surpassing all who were over Jerusalem before me, and my heart has had great experience of wisdom and knowledge.” 17 And I applied my heart to know wisdom and to know madness and folly. I perceived that this also is but a striving after wind.
18 For in much wisdom is much vexation,

What a heavy burden God has laid on mankind! 14 I have seen all the things that are done under the sun; all of them are meaningless, a chasing after the wind.
15 What is crooked cannot be straightened;
16 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.” 17 Then 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.
18 For with much wisdom comes much sorrow;
