9 So I was great, and increased more than all that were before me in Jerusalem: also my wisdom remained with me.
10 And whatsoever mine eyes desired I kept not from them; I withheld not my heart from any joy; for my heart rejoiced because of all my labor; and this was my portion from all my labor.
11 Then 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.
12 And I turned myself to behold wisdom, and madness, and folly: for what can the man do that cometh after the king?
13 Then I saw that wisdom excelleth folly, as far as light excelleth darkness.
14 The wise man’s eyes are in his head, and the fool walketh in darkness: and yet I perceived that one event happeneth to them all.
15 Then said I in my heart, As it happeneth to the fool, so will it happen even to me; and why was I then more wise? Then said I in my heart, that this also is vanity.
