Ecclesiastes 6:7-9 - One Must Learn To Be Content With What One Has
7 All the toil of man, is for his mouth, - though, even the desire, is not satisfied!
8 For what profit hath the wise man, over the dullard? What can, the poor man, know - so as to walk before the living? 9 Better what the eyes behold, than the wandering of desire, - even this, was vanity, and a feeding on wind.
