9 Better is the sight of the eyes than the wandering of the desire: this is also vanity and grasping after the wind.
10 Whatever has been is named already, and it is known that this is man: neither may he contend with him that is mightier than he.
11 Since there are many things that increase vanity, how is man the better?
12 For who knows what is good for man in this life, all the days of his vain life which he spends like a shadow? for who can tell a man what shall be after him under the sun?
