[12] 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. [13] Then I saw that wisdom excelleth folly, as far as light excelleth darkness. [14] The wise man's eyes are in his head; but the fool walketh in darkness: and I myself perceived also that one event happeneth [15] 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. [16] For there is no remembrance of the wise more than of the fool for ever; seeing that which now is in the days to come shall all be forgotten. And how dieth the wise man? as the fool. [17] Therefore I hated life; because the work that is wrought under the sun is grievous unto me: for all is vanity and vexation of spirit. [18] Yea, I hated all my labour which I had taken under the sun: because I should leave it unto the man that shall be after [19] And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This is also vanity. [20] Therefore I went about my heart to despair of all the labour which I took under the sun. [21] For there is a man whose labour is in wisdom, and in knowledge, and in equity; yet to a man that hath not laboured therein shall he leave it for his portion. This also is vanity and a great evil. [22] For what hath man of all his labour, and of the vexation of his heart, wherein he hath laboured under the sun? [23] For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity.
