I explored with my mind how to let my body enjoy life with wine and how to grasp folly—my mind still guiding me with wisdom—until I could see what is good for people to do under heaven during the few days of their lives.

He has made everything suitable in its time. He also has put {the past} in their hearts, yet no one can grasp what God does from the beginning to the end.

It is good that you grasp one thing and also not let go of the other; for the one who fears God comes forth with both of them.

I have examined all this by wisdom; I said, "I am determined to comprehend this" -- but it was beyond my grasp.

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