For who knows what is good for a man during the few days in which he passes through his fleeting life like a shadow? Who can tell a man what will come after him under the sun?

Ecclesiastes 8:7
Since no one knows what will happen, who can tell him what is to come?

Ecclesiastes 9:9
Enjoy life with your beloved wife all the days of the fleeting life that God has given you under the sun--all your fleeting days. For this is your portion in life and in your labor under the sun.

Ecclesiastes 10:14
Yet the fool multiplies words. No one knows what is coming, and who can tell him what will come after him?

For who knows what is good for man in this life, all the days of his vain life which he spends as a shadow? for who can tell a man what shall be after him under the sun?
