Ecclesiastes 2:21-23

International Standard Version

²¹ For sometimes people who strive to obtain wisdom, knowledge, and equity leave everything as an inheritance to a person who never worked for it. This, too, is pointless and greatly troublesome.

²² For what does a person gain from everything that he accomplishes and from his inner life struggles that he undergoes while working on earth? ²³ Indeed, all of his days are filled with sorrow, and his struggles bring grief. In fact, his mind remains restless throughout the night. This is pointless, too!
