Upon their exodus from Egypt, before their entry into the land of Israel, the Jewish people sent spies to scour the land and see what the people were like and what kind of battle would need to be fought.
But rather than encourage and strengthen their brethren telling them what a special and holy place it is. That this is a lush and bountiful land flowing with milk and honey. It's fruits are so large one grape could feed an entire family so there is no need for hard work, they could better use their time studying Torah. And most of all, it can be easily conquered as G‑d has commanded.
Instead, all but two of the spies warned that the inhabitants of the land are giants and warriors “more powerful than we”. The people wept that they’d rather return to Egypt.
G-d did not appreciate this treachery and promised as many a scolding parent would, because you cried for no purpose I will give you a reason to cry about. Indeed, the very day many years later became known as Tisha B'Av, the day when both Holy Temples were destroyed.
Each and every one of us too is a spy on a G-d given mission. To come down in to this world and "scour the land" seeking out the good and the G-dliness hidden in every part of this "land".
Will we view the bounty, the money and all worldly things as the "giants - more powerful than we" or will we find the tremendous opportunity in accomplishing our mission to realize that it can all be used for a greater, higher purpose given to man?
