Ecclesiastes 2:13 (KJV)

Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.

And 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 already done.

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

The wise man’s eyes are in his head; but the fool walketh in darkness: and I myself perceived also that one event happeneth to them all.

Then said I in my heart, As it happeneth to the fool, so it happeneth even to me; and why was I then more wise? Then I said in my heart, that this also is vanity.
