A massive military campaign by eastern empires sets out to crush a regional rebellion. In the fourteenth year of the local uprising against foreign rule, the decisive moment arrives [רש״י, ביאור יש״ר, שטיינזלץ]. Chedorlaomer spearheads the invasion as the primary architect of the operation, joined by his three allied kings [רש״י, ספורנו].
Rather than launching a direct assault on Sodom and its surrounding cities, the eastern armies execute a systematic, preemptive sweep of neighboring territories. Some explain that the invaders targeted these nations out of concern that they might form an alliance with the rebelling kings of Sodom [מלבי״ם], or because these lands were already under the jurisdiction of the rebels [בכור שור]. Another perspective suggests that the eastern kings originally intended only to war against these specific neighboring nations, and the king of Sodom merely ambushed them on their return journey to seize their spoils [שד״ל].
The primary approach among commentators is that the extensive catalog of conquered peoples and cities serves a greater purpose than mere historical record. It is designed to amplify the sheer might of the four kings, who successfully subdued nations of legendary giants dwelling in fortified cities. Establishing the undisputed power of these empires ultimately magnifies the heroism of Abraham, who later defeated these formidable forces with a small band of men and tactical ingenuity to rescue his nephew.
The campaign trail outlines a series of victories over terrifying populations. First, they struck the Rephaim, a nation of giants whose very appearance caused onlookers to freeze in mortal terror, as if they were looking at the dead [אבן עזרא]. Despite the devastation, a remnant of these giants survived the war [ברכת אשר]. This battle took place in Ashterot Karnaim, a heavily fortified valley situated between two towering, horn-shaped mountains that cast such deep shadows the sun barely reached the ground [רד״ק, מחוקקי יהודה]. Next, the army defeated the Zuzim, widely identified as the Zamzummim, a giant race inhabiting the region that would eventually become the land of Ammon. They were vanquished in a place called Ham [שטיינזלץ, אם למקרא]. Finally, the invaders crushed the Eimim, formidable warriors whose name itself reflects the overwhelming dread they cast upon their surroundings [אבן עזרא, רבנו בחיי]. They were subdued in the plains of Kiriathaim, a district that would later become the land of Moab [רבנו בחיי, מלבי״ם].
Beyond highlighting Abraham's bravery, the narrative of this war contains deeper legal and theological dimensions. One approach explains that detailing these conquests establishes the inheritance rights of Abraham's relatives. Because Abraham eventually defeated the four kings, he acquired the legal rights to all the territories they had conquered. This allowed the descendants of Lot and Esau to rightfully inherit their respective lands [הכתב והקבלה]. Another view sees this conflict as early divine intervention. God orchestrated the arrival of the eastern kings to punish and weaken these local nations for their sins, effectively preparing the land for its future conquest by the Israelites [ביאור יש״ר]. Finally, the specific mention of the fourteenth year carries a prophetic historical parallel: just as these mighty nations fell to Abraham, the Assyrian king Sennacherib and his massive armies would miraculously fall before Israel in the fourteenth year of King Hezekiah's reign [קיצור בעל הטורים].
