Look! I observed that it is good and prudent to eat, drink, and enjoy all that is good of a person's work that he does on earth during the limited days of his life, which God gives him, for this is his allotment.

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]?
