King David’s military campaigns were complex, multi-front battles that tested physical strength, strategic planning, and moral character. Following a major victory, David established a lasting legacy. The primary approach among commentators is that he gained widespread fame and a formidable reputation for his great acts of bravery [מצודת דוד, אברבנאל]. Some suggest he erected a physical monument to commemorate his conquests [ביאור שטיינזלץ]. However, a unique perspective reveals a different source for this renown. David's good name did not stem merely from military triumph, but from his profound wartime morality: he ensured that the fallen enemy soldiers received a respectful burial [רש"י, אברבנאל].
The timing of these battles highlights the extraordinary endurance of David's army. Even though the soldiers were exhausted from their initial campaign, they immediately continued to strike down another enemy on their return journey [מצודת דוד]. This sequence of events was the result of a calculated strategy by the army commander, Yoav. While the army was heading out to fight the nation of Aram, the nation of Edom provoked the Israelites and attempted to block their passage. Rather than destroying Edom immediately, Yoav chose to delay the confrontation. He wanted to ensure that his army would still have access to food and water in Edomite territory on their way back. Therefore, he waited until after defeating Aram before engaging Edom [רד"ק, אברבנאל].
Historical records of this conflict vary, with some accounts mentioning eighteen thousand fallen soldiers from Aram, while others cite twelve thousand from Edom, led by different commanders. Commentators resolve these differences in several ways. One approach suggests that Aram and Edom joined forces, resulting in a combined loss of twelve thousand Edomites and six thousand Arameans. The different records simply emphasize either the primary instigating nation or the nation that suffered the most casualties [מלבי"ם, רד"ק]. Another explanation divides the battle into stages led by different commanders. Avishai initiated the combat, defeating six thousand men, and Yoav completed the campaign by defeating an additional twelve thousand. The total victory is ultimately attributed to David, as he was the king and supreme commander overseeing the entire war [רד"ק, אברבנאל, מלבי"ם]. Alternatively, some scholars propose that these differing accounts actually describe two completely separate wars that occurred at different times [רש"י, מלבי"ם, רד"ק], though this view is not universally accepted [אברבנאל].
Ultimately, this triumph was recognized as the result of direct Divine intervention. God saved David and his army, and this success served as a sign for the future, hinting at a time when the Israelites would fully inherit the lands of these adversaries [מלבי"ם].
