Ecclesiastes 6:7-12

All the labor of man is for his mouth [for self-preservation and enjoyment], and yet the desire [of his soul] is not satisfied. [Prov 16:26] For what advantage has the wise man over the fool [for being worldly-wise is not the secret to happiness]? What advantage has the poor man who has learned how to walk [publicly] among the living [with men’s eyes on him; for being poor is not the secret to happiness either]? What the eyes see [enjoying what is available] is better than [craving] what the soul desires. This too is futility and chasing after the wind. Whatever exists has already been named [long ago], and it is known what [a frail being] man is; for he cannot dispute with Him who is mightier than he. For there are many other words that increase futility. What then is the advantage for a man? For who [limited by human wisdom] knows what is good for man during his lifetime, during the few days of his futile life? He spends them like a shadow [staying busy, but achieving nothing of lasting value]. For who can tell a man what will happen after him [to his work, his treasure, his plans] under the sun [after his life is over]?
