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

For he doesn't know that which will be; for who can tell him how it will be?

A fool also multiplies words. Man doesn't know what will be; and that which will be after him, who can tell him?

Don't curse the king, no, not in your thoughts; and don't curse the rich in your bedroom: for a bird of the sky may carry your voice, and that which has wings may tell the matter.
