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:
like chasing the wind!
There is nothing gained
2:22 What does a man acquire from all his labor
and from the anxiety that accompanies his toil on earth?
6:9 It is better to be content with
than for one’s heart always to crave more.
This continual longing
89:47 Take note of my brief lifespan!
Why do you make all people so mortal?
