Ecclesiastes 2:20-22

BRG Bible

²⁰ Therefore I went about to cause 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?
