9 It is better to enjoy the good that is present than the wandering of desire; this is also vanity and vexation of spirit.
10 He that is has been named already; and it is known that he is man and that he shall not be able to contend with him that is mightier than he.
11 Certainly the many words multiply vanity, what more does man have?
12 For who knows what is good for man in this life, all the days of the life of his vanity which he causes to be as a shadow? for who shall teach the man what shall be after him under the sun?
