machlokes, specifically the dispute that Korach initiated with Moshe Rabbeinu.
The
Medrash Tanchuma tells us that Korach was, in fact, very smart. Why did he choose to argue with Moshe Rabbeinu? Rashi explains that he resented the appointment of Elitzafan ben Uziel as a
Nasi. Korach noted that Kâhas had four children, the oldest of whom was Amram, and his two sons were already in positions of greatness: Moshe Rabbeinu was king and Aharon was the
Kohen Gadol. He, Korach, should be next in line as the son of Yitzhar instead of Elitzafan, who was the youngest of all.
