The spies were messengers of Moshe Rabbeinu. The Heilige Chiddushei HaRim adds that we are ALL messengers. Our neshamas have been sent to this world to fulfill certain tasks that ONLY we can accomplish. But a well known Jewish thinker once wrote the following line which rings so true for so many.
"Man is a messenger who forgot the message."
Good Shabbos Sweetest Friends!!:)
