민수기 8:3의 Musar

It had to be constructed in one solid piece. It could not be pieced together. This is an allusion to the close ties that ought to exist naturally between all Jews. Their affinity to one another should be natural. This explains why Rashi says that the verse telling us that Aaron did as he was told (8,2), was a compliment to him, commending him for not having departed from G–d's instructions. We could have assumed that it was natural for him to do what G–d had said, and why only here does the Torah state that he carried out his instructions? However, what the Torah wanted to stress is that Aaron was singularly suited to be the High Priest since he did not depart from the essence of what the Menorah symbolised, the unity of the Jewish people. In his capacity of being an אוהב שלום ורודף שלום, "a lover of peace and someone who actively pursued peace," he represented exactly what was needed.
