In the Portion we read today we come across the famous passage of VAYEHI BINSO’A HA’ARON which is recited whenever the Torah is removed from the Aron Kodesh. Whenever our people in the Wilderness would break camp and journey to the next site, the Aron would go before them. Moshe would say KOMAH HASHEM, “Rise up Hashem”. When they were to stop their journey and set up camp Moshe would say SHUVAH HASHEM, “Return Hashem”.
Rabbi Samson Rephael Hirsh points out that neither the starting nor the coming to rest occurred at Moshe’s orders. Yet Moshe accompanied these actions with his commands as if it depended on his will. Rabbi Hirsh in his famous commentary in “The Pentateuch” explains that Moshe was so ready to accept the Will of Hashem that it became as if it were his own will.
This is what we learn in “Pirke Avot” that Rabbi Gamliel says “Do His will as if it were your will”> (Avot 2;4) This is the essence of fulfilling a Mitzvah with full Kavanah. We are to perform the Mitzvah which came to us from Hashem as if it were our will as well. This is true belief.
