In these passages we learn the actual borders of the Promised Land, the land that God had given to His people. This land that God had given them the Israelites controlled for only a short period of time. The time that they had the most control was several centuries later when King David and Solomon ruled. The land is more than political borders as it is the land that God gave to His chosen people. God had also told them how the land was to be divided between the tribes. As we read in the last Chapter Reuben, Gad, and the half tribe of Manasseh had settled on the east side of the Jordan outside of the Promised Land.
The land was to be divided fairly between the tribes as God was a just God. God appointed leaders from each tribe to help Eleazar the High Priest and Joshua to distribute that land.
