דברים, פרק כ״ט, פסוק ז׳

The recent conquest and distribution of the territory east of the Jordan River stands as a powerful, immediate testament to God's guiding hand and the destiny of the Israelites. Because these acts of kindness occurred so recently, the people witnessed them firsthand. These undeniable facts make it impossible to overlook God's power [ביאור שטיינזלץ].

Awarding this territory to the two and a half tribes carries a deeper message regarding the nation's confidence in their future. By giving such a desirable, newly conquered area to a portion of the people—effectively replacing their share in the Land of Israel itself—it proves just how certain, guaranteed, and precious the actual Promised Land truly is [מלבי״ם].

Yet, beneath the surface of this land distribution lies a profound lesson about the limits of human understanding. What initially appears to be a great success and a cause for joy can eventually become a source of sadness, much like how moments of sorrow can ultimately bring about good [העמק דבר]. This reality is especially clear given Moses' prophetic awareness that these specific tribes would be the first to face exile from their land. Even knowing this, Moses did not prevent them from settling east of the Jordan, outside the primary borders. He allowed this settlement to teach the Israelites that in the distant future, their inheritance will expand to encompass the entire world. Furthermore, by walking through and settling these outer regions, Moses, the elders, and the Divine Presence left a lasting imprint. This ensured that even in times of future exile, the people would find places of rest where their ancestors had already established an enduring hold [שפתי כהן].
