The monumental task of dividing the land of Israel reaches a turning point, shifting focus from the nation as a whole to their devoted leader. The initial phase of distribution concludes once the territories are assigned to the tribes through a lottery system [מצודת דוד, מלבי״ם]. This step successfully establishes the broad regions and detailed borders for each specific tribe [מצודת דוד].
A brief pause occurs between this first stage and the upcoming second stage, which involves dividing the land further among individual families based on their population size. During this exact window of time, the Israelites choose to present a personal portion of land to Joshua [מלבי״ם]. Granting him his own property at this specific moment serves as a special tribute, given by the people in deep appreciation for his countless contributions and outstanding merits [ביאור שטיינזלץ].
