What benefit ¹  do people ²  get from all the effort which ³  they expend ⁴  on earth? ⁵ 

So I began to despair ¹  about all the fruit of ²  my labor ³  for which I worked so hard ⁴  on earth. ⁵ 

Yet when I reflected on everything I had accomplished ¹  and on all the effort that I had expended to accomplish it, ²  I concluded: ³  “All these ⁴  achievements and possessions ⁵  are ultimately ⁶  profitless ⁷  – like chasing the wind! There is nothing gained ⁸  from them ⁹  on earth.”

Who knows if he will be a wise man or a fool? Yet ¹  he will be master over all the fruit of ²  my labor ³  for which I worked so wisely ⁴  on earth! ⁵  This also is futile!

For a man may do his work with wisdom, knowledge, and skill; however, he must hand over ¹  the fruit of his labor ²  as an inheritance ³  to someone else who did not work for it. This also is futile, and an awful injustice! ⁴ 

This is another misfortune: ¹  Just as he came, so will he go. What did he gain from toiling for the wind?

I have seen personally what is the only beneficial and appropriate course of action for people: ¹  to eat and drink, ²  and find enjoyment in all their ³  hard work ⁴  on earth ⁵  during the few days of their life which God has given them, for this is their reward. ⁶ 

then I discerned all that God has done: ¹  No one really comprehends what happens ²  on earth. ³  Despite all human ⁴  efforts to discover it, no one can ever grasp ⁵  it. ⁶  Even if ⁷  a wise person claimed ⁸  that he understood, he would not really comprehend ⁹  it.
