2:11 Yet when I reflected on everything I had accomplished
and on all the effort that I had expended to accomplish it,
I concluded: “All these achievements and possessions are ultimately profitless –
like chasing the wind!
There is nothing gained from them on earth.”
4:4 Then I considered all the skillful work that is done:
Surely it is nothing more than competition between one person and another.
This also is profitless – like chasing the wind.
4:16 There is no end to all the people nor to the past generations,
yet future generations will not rejoice in him.
This also is profitless and like chasing the wind.
