Chapters 16 and 17 of Sefer Yehoshua spell out the tribal boundaries of Yosef. Yehuda and Yosef were the most important tribes in ancient Israel. Their pivotal tribal roles were already indicated by the Divinely-ordained arrangement of the camp of Israel, during the peregrinations in the wilderness. This lesson will explore the traditional roles of the two tribes in earlier sources, and the effect of these roles on the boundaries on the two tribes in the division of the land.
