The division of the land under Joshua's leadership was an exact and careful process, carried out in strict agreement with the instructions God had originally given to Moses. This careful execution sets the stage for the detailed assignment of territories to the nine and a half tribes settling on the western side of the Jordan River [ביאור שטיינזלץ].
Obeying God's instructions required close attention to several specific rules. Most importantly, the leaders had to follow the strict command to exclude the tribe of Levi from receiving a regular land inheritance. The land was distributed exclusively among the remaining tribes, ensuring that no territory was granted to the Levites [מצודת דוד].
Beyond this exclusion, the leaders carefully applied all the other practical rules of the land distribution. This included the vital instruction to grant larger territories to the tribes with larger populations, guaranteeing a fair and balanced settlement across the nation [מלבי״ם].
