17. 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.
18. And I hated all my labour wherein I laboured under the sun: seeing that I must leave it unto the man that shall be after me.
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 wisdom under the sun. This also is vanity.
20. Therefore I turned about to cause my heart to despair concerning all the labour wherein I had laboured under the sun.
21. For there is a man whose labour is with wisdom, and with knowledge, and with skilfulness; 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 a man of all his labour, and of the striving of his heart, wherein he laboureth under the sun?
23. For all his days are but sorrows, and his travail is grief; yea, even in the night his heart taketh no rest. This also is vanity.
