Ecclesiastes 6:11 in the King James Version
Seeing there be many things that increase vanity, what is man the better?
Context
10 Whatever has been, its name was given long ago; and it is known what man is; neither can he contend with him who is mightier than he.
11 For there are many words that create vanity. What does that profit man?
12 For who knows what is good for man in life, all the days of his vain life which he spends like a shadow? For who can tell a man what will be after him under the sun?
