‘Shelach et Ami’ ‘Let My People Go’! Moshe Rabenu’s famous rallying cry has often been quoted most famously in the large demonstrations around the world for Freedom of Russian Jewry. However the verse is always misquoted because it is quoted incompletely. The complete quote is ‘Let my people go and serve me.’ Shemot 9:1
Dr. Eric Fromm in his classic work Escape From Freedom’ posits the existence to two freedoms
distinguishes between freedom from (negative freedom) and freedom to (positive freedom).
Just as there is no vacuum even in outer space where there are still a few hydrogen atoms per cubic meter so too there no such thing as true freedom as it is always replaced by some kind of "slavery": or, as Fromm postulates, another dictatorship.
In the process of becoming freed from authority, we are often left with feelings of hopelessness until another authoritarian system replaces the old order with another of different external appearance but identical function for the individual: to eliminate uncertainty by prescribing what to think and how to act.
Moshe says to Pharaoh, Let my people go and serve me." Freedom from you will be immediately followed by freedom to serve G-d.
At the burning bush (Shemot 3:12) G-d promises Moshe “When you have brought the people out of Egypt, you will serve G-d on this mountain.”
The same word in Hebrew denoting slavery is the same word denoting service of G-d ‘avodah’.
This is the point the ‘wicked son’ is trying to make ‘mah ha’avodah hazot lachem’ In Egypt we were serving Pharoah and now we are serving G-d, nothing has changed except the master’s identity.
The true answer to this question is: Our new Master is the Creator of the Universe the most worthwhile Being to serve. This service will give our lives purpose and true meaning.
