Ecclesiastes 2:12-22

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 done long ago. Then I saw that wisdom excelleth folly, as far as light excelleth darkness. 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. 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. For of the wise man, even as of the fool, there is no remembrance for ever; seeing that in the days to come all will have been long forgotten. And how doth the wise man die even as the fool! So I hated life, because the work that is wrought under the sun was grievous unto me; for all is vanity and a striving after wind. And I hated all my labor wherein I labored under the sun, seeing that I must leave it unto the man that shall be after me. And who knoweth whether he will be a wise man or a fool? yet will he have rule over all my labor wherein I have labored, and wherein I have showed myself wise under the sun. This also is vanity. Therefore I turned about to cause my heart to despair concerning all the labor wherein I had labored under the sun. For there is a man whose labor is with wisdom, and with knowledge, and with skilfulness; yet to a man that hath not labored therein shall he leave it for his portion. This also is vanity and a great evil. For what hath a man of all his labor, and of the striving of his heart, wherein he laboreth under the sun?
