יהושע, פרק י״ב, פסוק ז׳

Taking control of the land was an ongoing process. The recorded list of defeated kings and captured areas focuses specifically on Joshua's military victories west of the Jordan River [ביאור שטיינזלץ]. Detailing the exact kings who were defeated serves a clear purpose. It shows that this record does not include the entire land. Instead, it only outlines the specific regions Joshua actually managed to conquer during his lifetime, as large territories still remained unconquered [מלבי״ם].

When the land was handed over to the tribes, it was given according to their divisions. This means the distribution was arranged based on how the tribes would eventually divide the territory among themselves in the later stages of their settlement [ביאור שטיינזלץ].
