I considered all the living who walk on earth, as well as the successor who would arise in his place.

What they loved, as well as what they hated and envied, perished long ago, and they no longer have a part in anything that happens on earth.

I decided to carefully and thoroughly examine all that has been accomplished on earth. I concluded: God has given people a burdensome task that keeps them occupied.

I thought deeply about the effects of indulging myself with wine (all the while my mind was guiding me with wisdom) and the effects of behaving foolishly, so that I might discover what is profitable for people to do on earth during the few days of their lives.

So I again considered all the oppression that continually occurs on earth. This is what I saw: The oppressed were in tears, but no one was comforting them; no one delivers them from the power of their oppressors.

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

For no one knows what is best for a person during his life – during the few days of his fleeting life – for they pass away like a shadow. Nor can anyone tell him what the future will hold for him on earth.

While applying my mind to everything that happens in this world, I have seen all this: Sometimes one person dominates other people to their harm.

This is the unfortunate fact about everything that happens on earth: the same fate awaits everyone. In addition to this, the hearts of all people are full of evil, and there is folly in their hearts during their lives – then they die.

Again, I observed this on the earth: the race is not always won by the swiftest, the battle is not always won by the strongest; prosperity does not always belong to those who are the wisest, wealth does not always belong to those who are the most discerning, nor does success always come to those with the most knowledge – for time and chance may overcome them all.

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.
