Ecclesiastes 6:9KJV

7All the labour of man for his mouth, and yet the appetite is not filled.

8For what hath the wise more than the fool? what hath the poor, that knoweth to walk before the living?

9Better the sight of the eyes than the wandering of the desire: this also vanity and vexation of spirit.

10That which hath been is named already, and it is known that it man: neither may he contend with him that is mightier than he.

11Seeing there be many things that increase vanity, what man the better?
