New International Version
21 For a person may labor with wisdom, knowledge and skill, and then they must leave all they own to another who has not toiled for it. This too is meaningless and a great misfortune. 22 What do people get for all the toil and anxious striving with which they labor under the sun?(A) 23 All their days their work is grief and pain;(B) even at night their minds do not rest.(C) This too is meaningless.
