The Elohist narrator was creadited with making Aaron the brother and helper of Moses, who stood at the side of Moses in the conflict with the Pharaoh and assisted him as a leader in battles and in the cult. It may also be the Elohist who provides the unfavorable story about Aaron’s objection to Moses’ who mentions Aaron at the side of Moses in the revolt at Meribah, but here also Aaron, together with Moses, is actually reproached.
There is reason to believe that the original author but that his name has been added by a redactor. The main bulk of the traditions about Aaron and the frequent addition of “and Aaron” after the mention of Moses are found in the Priestly source, which was written at a time when the priests had a more dominant position in Judah than they had before the exile. By then Moses had ceased to be the hero of the priests, and Aaron had taken over that role.
Many modern scholars prefer to speak of traditions and layers of traditions where their predecessors spoke of sources, but apart from this terminology, the view concerning Aaron has not greatly changed. There have been new attempts, however, to see the contrasting figures of Moses and Aaron in a new light. It has been suggested that the tradition, about Moses represent a southern Judean tradition, while the old traditions about Aaron originated in the northern kingdom.
It has also been indicated that the traditions about Moses are primarily concerned with a prophet, while those about Aaron are connected with priesthood. There may be a kernel of truth in all these suggestions, as also in the theory of Ivan Engnell that Moses represents the royal ideology while Aaron stands for priesthood and priesthood alone. The standing struggle between the king and the leading priest is reflected both in the laws and in the narratives of the historical books.
