All human toil is for the mouth, yet the appetite is not satisfied.
For what advantage have the wise over fools? And what do the poor have who know how to conduct themselves before the living?
Better is the sight of the eyes than the wandering of desire; this also is vanity and a chasing after wind.
References for Ecclesiastes 6:9
Whatever has come to be has already been named, and it is known what human beings are, and that they are not able to dispute with those who are stronger.
The more words, the more vanity, so how is one the better?
For who knows what is good for mortals while they live the few days of their vain life, which they pass like a shadow? For who can tell them what will be after them under the sun?
