Ecclesiastes 2:18-23

JPS_ASV_Byz(i) 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 will be a wise man or a fool? yet will he have rule over all my labour wherein I have laboured, and wherein I have shown myself wise 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 skill; 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 pains, and his occupation vexation; yea, even in the night his heart taketh not rest. This also is vanity.
