Ecclesiastes 2:21-23

New King James Version

²¹ For there is a man whose labor is with wisdom, knowledge, and skill; yet he must leave his ^[a]heritage to a man who has not labored for it. This also is vanity and a great evil. ^22 (A)For what has man for all his labor, and for the striving of his heart with which he has toiled under the sun? ²³ For all his days are ^(B)sorrowful, and his work burdensome; even in the night his heart takes no rest. This also is vanity.
