Ramban: HaChodesh: The Month of The Patriarchs
In essence, the Book of Shemot spans the Jewish people’s exile and redemption. It begins with the descent of Yaakov and his household to Egypt and concludes with the exodus of our entire nation. Yet, almost half of the sefer is devoted to the intricacies of the Sanctuary, something seemingly unrelated to redemption!
Nachmanides explains that the Jewish redemption extended far beyond the physical boundaries of Egypt. Before they left the land of Israel, Yaakov and his sons enjoyed a close relationship with Hashem. The devotion of the Patriarchs had produced such an intense level of sanctity that Hashem’s presence was commonplace amongst them. However with their descent to Egypt, this experience faded away and, to some degree, distance developed between themselves and Hashem. Over the hundreds of years in Egypt, this distance grew and they eventually lost all association with! Him.
Nachmanides explains that even after their liberation from Egyptian bondage, scars of exile remained deeply imprinted on them. Having left Egypt, they began rebuilding their relationship with Hashem and prepared for a long journey homeward to Him. Finally, with the erection of the Sanctuary, they reached their ultimate destiny and reunited with Hashem.
The Sanctuary created a tangible experience of Hashem’s presence amongst them, the clearest indication of His reunification with them. With this final development, the Jewish people’s redemption was complete. They now returned to the status of the Patriarchs, and were totally bound to their Creator. All scars of their exile disappeared and they could now, enjoy the closest relationship with their beloved, Hashem.
This perspective is best reflected in the words of Chazal in P’sikta Rabbatti. Our Chazal inform us that, in reality, all the segments of the Sanctuary were already completed in the month of Kislev. However, Hashem waited until Nissan which is called “the month of the Patriarchs”, for the erection and inauguration of the Mishkan. With the insight of Nachmanides we can appreciate the message of this P’sikta. As stated, the erection of the Sanctuary represented the completion of our Jewish redemption,their reunification with Hashem.
In fact, this unification was so intense that it was tantamount to the glorious relationship of the Patriarchs and Hashem. In essence this present Jewish status reflected that of the Patriarchs in whose merit this relationship had been reinstated. It was therefore only proper to wait until Nissan for the dedication of the Sanctuary. Nissan which was the month of the Patriarchs was reserved for this dedication, because it reflected the Jewish people’! s parallel level to the Patriarchs themselves.
