Divine providence presents a fascinating duality. On one hand, God exists entirely beyond the confines of time and space as the supreme, eternal source of power. On the other hand, He is deeply and actively involved in the physical world, intimately supporting the Israelites and fighting their battles. As the eternal God who predates the creation of time, space, and the universe itself [רש״י, אבן עזרא, ספורנו, רא״ש], He offers a multifaceted protection to His people.
The primary approach among commentators is that God serves as a spiritual shelter and a supreme refuge, directly shielding the Israelites from harm [אבן עזרא, שד״ל, הטור הארוך, רבנו בחיי, ביאור יש״ר, ביאור שטיינזלץ]. Others suggest that this protection emanates from His own celestial dwelling place in the heavens, which He established as His permanent residence [רש״י, רא״ש, דעת זקנים, חזקוני, בכור שור, נתינה לגר, דברי דוד]. Taking a profoundly different perspective, some explain that the Israelites themselves are the very dwelling place where God chooses to rest His Divine Presence [העמק דבר, צרור המור]. Furthermore, this shelter is not merely passive. It is intertwined with Divine providence, representing God's watchful eye constantly looking over the nation [הכתב והקבלה], while simultaneously hinting at the strict Divine judgment unleashed against their enemies [פני דוד, רבנו בחיי].
Below this heavenly protection, God's eternal arms provide a foundation for all of existence. Just as He shields the Israelites from above, His everlasting arms support and carry the entire world from below, ensuring it does not collapse [אבן עזרא, שד״ל, רבנו בחיי, רש ר הירש, ביאור יש״ר, ביאור שטיינזלץ]. These arms symbolize the natural systems and forces through which God guides reality and sustains human life [ספורנו, מלבי״ם, נתינה לגר]. Alternatively, they represent the spiritual pillars of the world, namely the Patriarchs, the righteous, and the humble, whose merit actively keeps the world in existence [צרור המור, תורה תמימה, פני דוד].
Shifting the focus from Divine support to earthly power, another interpretation views this foundation as a declaration of subjugation over enemies. Beneath God's lofty seat reside the mighty rulers of the earth, such as Sihon and Og. Though they are considered the powerful arms of the world due to their strength, they are ultimately weak and trembling before Him [רש״י, מזרחי, הכתב והקבלה]. Even during periods of bitter exile, when the Israelites find themselves crushed beneath the yoke of these worldly powers, the Divine Presence remains steadfastly with them [העמק דבר].
This active Divine presence manifests clearly in history through God's tangible intervention in the Israelites' wars against nations like Amalek, Canaan, Midian, Sihon, Og, and Haman [רא״ש, דעת זקנים, חזקוני, אדרת אליהו, ביאור יש״ר, העמק דבר, פני דוד]. In these conflicts, a unique division of labor unfolds. God is the one who actively drives out the enemies through the sheer power of His word, often causing them to flee on their own accord [צפנת פענח, מלבי״ם, נתינה לגר]. Yet, He turns to the Israelites and commands them to destroy the enemy, tasking them with completing the physical work of the battle [שפתי חכמים, ביאור יש״ר, רא״ש]. Unlike mortal kings who greedily hoard the glory of victory for themselves, God deliberately steps back. He grants the Israelites the privilege of being called the victors and allows them to claim the triumph in their own name, even though the salvation and the power are entirely His [צרור המור, ספורנו].
