Ecclesiastes 2:20-22 American Standard Version (ASV)
20 Therefore I turned about to cause my heart to despair concerning all the labor wherein I had labored under the sun. 21 For there is a man whose labor is with wisdom, and with knowledge, and with [a]skilfulness; yet to a man that hath not labored therein shall he [b]leave it for his portion. This also is vanity and a great evil. 22 For what hath a man of all his labor, and of the [c]striving of his heart, wherein he laboreth under the sun?
