פירוש על יהושע 19:9

Was too large for them. It was more than was their due.²Various reasons are presented why Shimon was given part of their inheritance in the midst of Yehudah’s territory. Some say that Shimon helped Yehudah conquer their land and therefore merited to receive some of it as their own. Others maintain that this was because Yaakov had said: “Shimon and Levi are brothers, instruments of violence are their wares. I will disperse them throughout Yaakov and scatter them throughout Israel.” (Bereishis 49:5,7) Shimon was given a portion within Yehudah and Levi was scattered throughout many cities in the land.
