What I Can Learn From the Children Of Israel

Don't take more than you need.
Whining only vexes those in charge and doesn't change anything.
Better develop a taste for your particular "manna".
Don't die before Promised Land opens up.
Wandering without a purpose is one way to live a life.
The new trial of wandering was better than the old trial slaving.
Don't listen to the spies.
Time passes whether you enjoy it or not.
