במדבר, פרק כ״א, פסוק ל״ד

As the Israelites near the end of their desert journey, they stand on the brink of a daunting military campaign. God speaks directly to Moses, commanding him not to be afraid. This divine reassurance reveals a deep, underlying anxiety within the leader that required special intervention. Moses was not intimidated by the sheer physical might of Og, the King of Bashan, even though Og was a remnant of an ancient race of giants possessing immense natural strength [רמב״ן, רבנו בחיי, תולדות יצחק, ביאור שטיינזלץ]. A prophet who carries the presence of God does not cower before flesh and blood. Instead, his hesitation stemmed from profound spiritual and strategic concerns. This raises a compelling question: why did God need to explicitly reassure Moses before facing Og, when no such warning was given before the previous battle against Sihon [מזרחי, תורה תמימה]?

The primary approach among commentators is that Moses feared a specific historical merit that Og possessed. According to tradition, Og was the lone survivor who brought news to Abraham that his nephew Lot had been captured in battle. Moses, fully aware of Og's extraordinarily long life spanning centuries, worried that Abraham's merit would now serve as a shield for the giant. Yet, this presents a moral difficulty, as Og’s original intention was entirely malicious. He delivered the news hoping Abraham would be killed in battle, leaving Sarah available to marry him. How could such sinister motives yield a protective merit? Some explain that because the act ultimately led to Lot's rescue, God rewarded Og for his physical effort with a prolonged life. This mirrors the dynamic of Balak, who was rewarded with a righteous descendant for the sacrifices he offered, despite his intention to curse the Israelites [שפתי חכמים, פענח רזא, דעת זקנים, חזקוני, הדר זקנים]. Alternatively, Moses himself may not have known Og's true, dark intentions. Fearing that the giant might have acted out of genuine kindness, Moses hesitated until God reassured him [כלי יקר].

Beyond the merit of bringing news to Abraham, other spiritual anxieties troubled Moses. One perspective suggests that the fear was not about Og at all, but rather a concern that the Israelites might have sinned and spiritually tainted themselves during their recent war with Sihon, thereby forfeiting their divine protection [רמב״ן, צאינה וראינה]. Another tradition links the apprehension to the fact that Og was circumcised alongside Abraham’s household, causing Moses to fear the protective power of that covenant [שפתי כהן].

Alongside these spiritual concerns lay a practical, strategic dilemma. Moses had no immediate intention of fighting Og or conquering his territory, as it was not strictly necessary for entering the Land of Israel. While Sihon had actively attacked the Israelites, forcing a conflict, Og had merely amassed his troops at his border city. The Israelites could have easily bypassed his territory and continued their journey, just as they had previously circumvented the land of Edom. Because Moses hesitated to initiate an unprovoked war, God had to command him to cast aside his fear and engage in battle, revealing that conquering this land was an essential part of the divine plan [רמב״ן, הטור הארוך, העמק דבר].

God's reassurance was highly specific, focusing solely on Og as an individual rather than his entire nation, because Moses' anxiety centered on the king's personal spiritual merit, not his military force [כלי יקר]. Furthermore, God framed His promise of victory as an event that had already occurred in the past. Speaking of the future as if it has already happened is characteristic of divine prophecies, underscoring the absolute certainty of their fulfillment [ביאור יש״ר]. It also reveals that Og's doom had been sealed long ago during the days of Abraham and Jacob, whom he had disrespected. God was assuring Moses that Og never possessed any true, enduring merit that could save him [כלי יקר, שפתי כהן].

The divine message concludes by comparing the impending victory to the defeat of Sihon. Even though Sihon and Og were brothers who shared the same supernatural origins [רבנו בחיי, דעת זקנים, הדר זקנים], Og was destined for the exact same downfall. The defeated Sihon is still described as the current ruler of Heshbon, either because it reflects where he used to reign, or because fallen monarchs continue to be identified by their capital cities [ביאור יש״ר, ברכת אשר על התורה]. With these reassurances, Moses was directed to march into battle with absolute confidence, entirely nullifying whatever historical merit Og had once earned [תולדות יצחק, רבנו בחיי].
