Ecclesiastes 2:11-13

¹¹Then I looked on all the works that my hands had wrought, and on the labor that I had labored to do; and, behold, all was vanity and a striving after wind, and there was no profit under the sun.

¹²And I turned myself to behold wisdom, and madness, and folly: for what can the man do that cometh after the king? even that which hath been done long ago.

¹³Then I saw that wisdom excelleth folly, as far as light excelleth darkness.
