So I just started talking out this vort to him waiting for the question to pop up. My question wasn't on this. The Ohr Gedalyahu explains that although physically it took Bnei Yisrael one time to leave Egypt, spiritually they would have to leave 50 times. Maybe this has something to do with the exodus being mentioned in the Torah 50 times. Also, this can be one idea behind the 50 days till Mt. Sinai.
Every day is another time out.
Kindness within kindness. Taking care of 4 families of orphans certainly indicated their success making that first step. Bamidbar the daughters of Tslafchad heard the inheritance of Israel was to be portioned out according to the males of the family. The 5 daughters came to Moshe saying that their father died in the desert of his own sins and they have no brothers. They asked that their fathers name not be forgotten and that they get a portion of Israel.
