As his life draws to a close, Moses delivers a sobering message to the Israelites, confronting them with a profound reflection on their own rebellious nature and stubbornness. He presents a simple but striking logical argument: if they struggled to remain faithful while he was actively leading them, the challenge will only intensify once he is gone. Moses emphasizes that this assessment stems from his intimate, personal experience with the people's character, rather than from divine prophecy. By framing this as a logical deduction, he preemptively dismantles any future excuses the Israelites might make. They cannot claim their future failings were preordained by Heaven, and thus their absolute free will is preserved [צרור המור, ביאור יש״ר]. Recognizing this ingrained tendency, Moses realizes the necessity of appointing eternal witnesses, such as the heavens and the earth, to continually warn and guide the nation [בכור שור, צרור המור].
Moses identifies two fundamental flaws in the nation's character. The first is a deliberate rebelliousness, an intentional drive to act against God's commands [העמק דבר, ביאור שטיינזלץ]. The second is an innate stubbornness—a rigid quality that makes it difficult for them to humble themselves and accept divine authority [העמק דבר, בכור שור, ביאור שטיינזלץ]. Yet, commentators view this stubbornness as a deeply complex, double-edged trait. While it breeds skepticism and makes obedience difficult, it is also the very quality that makes them suited to be a chosen people. This unyielding nature shields them from the allure of foreign beliefs and prevents them from being gullible. Throughout history, it is this exact stubbornness that sustains the Israelites in exile, giving them the strength to endure suffering and sacrifice their lives rather than abandon their faith [אם למקרא]. Furthermore, even in moments of failure, this stubbornness fuels a deep desire to remain part of the nation. Consequently, rather than abandoning their religion entirely, they might twist the interpretation of the Torah to justify their actions, clinging to their identity even in sin [מלבי״ם].
The nature of their defiance is particularly striking because it occurred despite their close proximity to God. The primary approach among commentators is that the Israelites rebelled even while the Divine Presence rested openly in their camp and they were under direct divine providence [העמק דבר]. This dynamic reveals a nuanced reality about the nation: just as their loyalty is never entirely absolute, neither is their rebellion. Even in the midst of defiance, they remain tethered to God [רש ר הירש]. At times, they even rebel under the illusion that they are fulfilling His will and acting righteously, as seen during the uprising of Korah [מלבי״ם]. Reflecting on their past behavior also reveals that their rebellion was never a unanimous national consensus, but rather the actions of many individuals [העמק דבר]. Framing their defiance as a matter of the past leaves room for the hopeful possibility that, at the exact moment Moses was delivering his rebuke, the Israelites were already silently contemplating repentance [אור החיים].
Recognizing that this is his final day, Moses points out that while he is currently alive and present with them, a profound shift is imminent. Because the righteous are considered to be living even after they pass away, Moses clarifies that while his spiritual life will continue indefinitely, his physical presence alongside them in this world is about to end [אור החיים]. Looking ahead to the era after his passing, Moses anticipates a time when the open, manifest closeness to God experienced in the desert will fade. In the routine of ordinary life, the people will face the overwhelming temptation to assimilate and live like the surrounding nations, which ultimately leads to abandoning God's path [העמק דבר, ביאור שטיינזלץ]. However, this spiritual decline does not occur immediately. The warning about the period following his death actually refers to the era after the passing of Joshua and the elders. Because these subsequent leaders were direct disciples of Moses, as long as they lived and guided the nation, it was as if Moses himself were still alive among the people [אבן עזרא, ברטנורא על התורה].
