Ecclesiastes 2:11-14

¹¹Then I looked on all the works that my hands had wrought, and on the labour that it had cost me to do them; and behold, all was vanity and pursuit of the wind, and there was no profit under the sun.

¹²And I turned myself to behold wisdom, and madness, and folly; for what shall the man do that cometh after the king? — that which hath already been done.

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

¹⁴The wise man's eyes are in his head, and the fool walketh in darkness; but I myself also perceived that one event happeneth to them all.
