Moshe Weissman, “The Midrash Says,” Chapter “Shemini”: “Moshe said to his brother Aaron: ‘When I was appointed interim High Priest for seven days of the Consecration, I cherished the secret hope that I will be allowed to perpetuate this position for myself forever.
But because, I, at first refused to fulfill the request of the Almighty to take the Jews out of Egypt, I am not allowed to be the High Priest. And so this post is transferred to you, Aaron.
My brother, how can I do that to you? – Aaron pleaded. – How can I be a High Priest after you spent so much effort on the construction of the Mishkan?’
Moshe replied: When you heard that the Creator had chosen me to lead the Jewish people you rejoiced; so I am also happy that you will perform the duties of the High Priest.”
If we regard this conversation from a purely psychological point of view, we would most likely think that this passage is about a dialog between two different people. In fact, this conversation takes place inside one person, since Moshe and Aaron symbolize two opposite qualities in a man.
Aaron stands for the left part, and Moshe the right line. By nature, they are incompatible. That’s why they work separately.
Even though they are brothers and are united, there is always a gap and a connection between brothers. This passage shows us how to use both properties to make a positive impact on everybody around.
Moshe is a property of bestowal and love; it symbolizes a proximity to Abraham. Aaron denotes an internal tension, a bad quality that naturally overcomes itself and works for the Creator. Both properties are meant to replenish each other.
