שמות, פרק י״ז, פסוק י״ג

The clash with Amalek ends not in total annihilation, but in a decisive, calculated victory. The physical confrontation on the battlefield reflects a multi-dimensional struggle blending natural combat, Divine intervention, and hidden spiritual forces. Commentators debate the exact nature of the enemy's defeat. One approach suggests a complete and lethal victory, equating the enemy's downfall with total destruction and death [אבן עזרא, בכור שור, חזקוני, רשב״ם, הדר זקנים, אבן עזרא הקצר, ביאור יש״ר, ביאור שטיינזלץ]. Conversely, a primary approach maintains that Joshua did not entirely destroy the opposing army, but rather crippled it, striking down the mighty warriors while deliberately leaving the weaker soldiers alive [רש״י, מזרחי, צאינה וראינה, שפתי חכמים, דברי דוד].

Sparing the weak defied conventional military strategy, proving that Joshua acted strictly upon a precise command from God rather than standard tactical logic [רש״י, מזרחי, שפתי חכמים, גור אריה, ברכת אשר, רקנאטי]. This limited victory also carried long-term implications. The final eradication of Amalek was delayed to the distant future because the Israelites were not yet spiritually mature. They would need to continue struggling against this nation until they reached full spiritual adulthood [רש״ר הירש]. Additionally, leaving the enemy in a weakened state serves as a form of poetic justice, echoing how Amalek initially targeted the most vulnerable and exhausted Israelites at the start of their journey [קאסוטו].

Beneath the surface of physical combat, the battle involved complex mystical elements. Amalek carefully selected soldiers who, according to astrological alignments, were not destined to die that day, and utilized dark spells to render them immune to fatal sword strikes. Because of this, Joshua could not kill them outright, but could only sever their limbs to incapacitate them [הטור הארוך, דעת זקנים, חזקוני]. Alternatively, Joshua utilized holy names to dismantle their sorcery [פני דוד], while other traditions suggest the enemy was overcome through the casting of lots [הדר זקנים, דעת זקנים]. From a higher celestial perspective, God generally refrains from entirely overturning the laws of nature and astrological systems except in extreme circumstances. Therefore, He chose to diminish the enemy's power rather than completely uprooting the natural order [רבנו בחיי, תולדות יצחק].

The forces arrayed against the Israelites were vast and complex. Amalek did not fight alone, but brought along an allied nation or a gathered coalition [ספורנו, רלב״ג, קאסוטו], which may have included the broader masses and children of their society [הדר זקנים]. The conflict also raged in the heavenly realms. The victory encompassed the weakening of Amalek's spiritual guardian angel, an achievement made possible by the power of Moses's prayer [רבנו בחיי, תולדות יצחק].

Ultimately, the triumph was secured through natural, physical warfare rather than through an open miracle, plague, or sudden panic, as seen in other biblical battles [העמק דבר, מלבי״ם]. The specific reliance on the sword was intentional and deeply symbolic. The sword represented the historical blessing and inherent strength of Esau, Amalek's ancestor. To truly defeat his descendants, the Israelites had to confront and overcome them using that exact same weapon [אלשיך].
