Jacob says "I will separate them ("A'chalkaym") within Jacob, and disperse them (A'phitzaym) within Yisrael. There must be a nuanced difference between the 2 Hebrew verbs used here. It seems that one refers to Jacob, thus more physical reality, meaning their portion (chalak refers to portioning), their territory will be scattered out amongst the other tribes, that neither tribe will be given intact territory to settle. We suspect that the other verb, (Patzah) refers to the dispersement of their spiritual missions (Yisrael referring more to the spiritual realm). Thus, the Levites were dispersed territorially, with cities of refuge within the territories of the other tribes, and their spiritual mission was to serve as the spiritual caretakers of the tabernacle and temple for the sake of all the tribes. The tribe of Shimon was similarly dispersed within the tribal territory of Judah, without an intact territory of its own, though his spiritual mission and its reason for dispersal seems less clear. What was Levi’s saving grace, that despite his participation in the slaughter at Shechem, his descendants are given such a critical spiritual role amongst the Nation?
