People who are successful deserve credit - at least a nice pat on the back. They should receive appreciation and thanks. We don't see this given to Aaron. Even worse - his big brother gets all the credit for his actions and activities. This concept of the big brother is another difficulty that Aaron faces.

After all, the younger brother was selected to lead the Children of Israel out of Egypt, despite his inability to speak properly. Aaron, the bigger brother, was expected to take orders from Moses and then to get short shrift of everything that occurred afterwards.
