The enduring bond between good people and the land they inherit is a direct reflection of divine justice. God established a fixed law of truth in the world, and the promise of a permanent home for the righteous is the ultimate expression of His judgment [אבן עזרא].
This right to inherit the land does not require an unreachable standard of perfection. It is granted to those who maintain a fundamental level of righteousness, simply taking care to avoid sin, even if they do not achieve the highest levels of extreme piety. This stands in sharp contrast to the wicked who actively rebel and cause harm [אלשיך].
To reinforce this message, the promise of remaining on the land permanently is repeated conceptually. Rather than introducing a new idea, this repetition serves to strengthen the assurance given to good people. It highlights the absolute stability, enduring existence, and permanent reward that awaits them, ensuring their goodness is established for all time [רד״ק, מאירי].
