[:en]No one knows the future:
“Since no man knows the future, who can tell him what is to come? No man has power over the wind to contain it; so no one has power over the day of his death” (vs. 7-8)
No one knows what God is going to do:
“No one can comprehend what goes on under the sun. Despite all his efforts to search it out, man cannot discover its meaning. Even if a wise man claims he knows, he cannot really comprehend it” (vs. 16-17)[:]
