An instruction immediately subsequent to this orders that, once this is done, the Israelites should split into two groups, one to stay on Mount Ebal and pronounce curses, while the other goes to Mount Gerizim and pronounces blessings. The tribes of Simeon, Levi, Judah, Issachar, Joseph and Benjamin were to be sent to Gerizim, while those of Reuben, Gad, Asher, Zebulun, Dan and Naphtali, were to remain on Ebal. No attempts to explain this division of tribes either by their Biblical ethnology or by their geographical distribution have been generally accepted in academic circles. More recently, however, some argue that the tribes were divided as equally as possible given the population's census data given in the Book of Numbers. Specifically, the division found in the book of Deuteronomy is the most equal out of 462 possible divisions.
