Recognizing God's presence and His active guidance in the world naturally leads a person to accept the responsibility of His commandments. Observing these laws is not merely a duty; it is the ultimate purpose of the Exodus from Egypt and the sole condition for inheriting and living in the land [ספורנו, העמק דבר, מלבי״ם]. When a person truly knows their Creator, they follow His laws without hesitation [ספורנו]. The Torah and its practical commandments establish necessary boundaries and life missions, serving as the very channels through which God watches over and directs humanity [רש״ר הירש, העמק דבר].
Just as a physical city of refuge takes in and protects a person fleeing to it, the Torah and its commandments act as a spiritual shelter and shield for those who observe them [קיצור בעל הטורים]. The reward for this dedication exists on two distinct levels. The promise of goodness points to spiritual and heavenly rewards, while the promise of a long life guarantees physical blessings on earth [ביאור יש״ר], ensuring a person lives fully and does not die prematurely [אור החיים]. Furthermore, the laws given to Israel are eternal and will never be replaced or altered into a new religion [ספורנו].
The primary approach among commentators highlights the permanent nature of the gift of the land. Moses wanted to prevent the mistaken belief that the land was given for a limited time, much like a human lifespan; therefore, he emphasizes that the gift is forever [אור החיים]. Even during times of exile, when the Israelites are scattered among their enemies, their right to the land of Israel never ceases, and God will never abandon them [אם למקרא]. However, while the land is designated for Israel eternally, the ability to actually live there depends entirely on observing the commandments and remaining faithful to their purpose [רש״ר הירש]. Because Moses delivers these instructions while the people are still in the Transjordan, it reveals that the holiness of the land extends to this region as well, meaning it should not be viewed merely as conquered territory [ביאור שטיינזלץ]. Offering a different perspective, some commentators suggest that the promise of permanence does not refer to the giving of the land itself. Instead, it connects back to the previous blessing of a long life, guaranteeing that a person will enjoy those extended years continuously [שד״ל].
