Returning from the battlefield against the nation of Midian, the military commanders deliver a report to Moses that defies all natural logic. After engaging in combat with a massive enemy force, the army remains entirely intact. The commanders conduct a census of the troops under their authority, standing shoulder to shoulder with the common soldiers rather than separating themselves by rank [שד״ל]. The primary approach among commentators is that this outcome reflects an extraordinary miracle. Despite fighting an enemy army as vast as the sand on the seashore, not a single Israelite soldier was killed or even wounded by a sword [רמב״ן, הטור הארוך, רבנו בחיי, תורה תמימה, צאינה וראינה, ביאור שטיינזלץ]. Recognizing this miraculous survival, the officers feel a profound obligation to thank God on behalf of the entire nation and present an offering [העמק דבר].
Beyond the obvious dangers of combat, the soldiers faced another hidden threat. Taking a census of the troops carried the risk of triggering a plague, a consequence that occasionally follows counting the people. Therefore, the report that no one is missing highlights a dual salvation. Not only were the soldiers protected from the enemy weapons, but they were also spared from any plague that might have resulted from the count. Their offering serves as a ransom for their souls, specifically intended to protect them from this potential affliction [רשב״ם, חזקוני, מלבי״ם, בכור שור].
On a deeper level, the commanders report a remarkable spiritual victory. The complete presence of the troops indicates that not a single soldier engaged in forbidden relations with the Midianite women; they all maintained their absolute righteousness [רמב״ן, אור החיים, רבנו בחיי, בכור שור, חזקוני, צאינה וראינה]. This purity, however, raises a difficult question. If the men were so righteous and completely avoided sin, why did they need to bring an offering of atonement, particularly one made of women's jewelry? The commentators explain that the offering was not meant to atone for physical actions, but rather for the lustful thoughts that may have crossed their minds during the conflict [רמב״ן, אור החיים, רבנו בחיי, בכור שור]. Such sinful thoughts can sometimes be more agonizing than the sin itself. While a physical act eventually comes to an end, thoughts of desire can continuously torment a person day and night. It was precisely for this internal struggle that the soldiers sought atonement [צאינה וראינה].
