דברי הימים א, פרק י״ח, פסוק י״ג

David's conquest of Edom marked a major strategic and economic turning point in his military campaigns. Rather than applying his usual foreign policy, David established a uniquely direct and tight grip over this newly conquered territory. Instead of leaving a local king in power or appointing a ruler from the native population, he installed his own Israelite governors to manage the region [רש״י, ביאור שטיינזלץ]. Through these appointed officials, the entire population of Edom was brought into direct submission under David's rule.

The motivation behind this unusually strict governance was Edom's vast economic value. The region held significant wealth and influence due to its rich copper mines and its control over crucial trade routes leading toward the Red Sea [ביאור שטיינזלץ]. Securing these assets required absolute authority over the area. Yet, the consistent military and political achievements that allowed David to secure such vital territories were not merely the result of his own strategy. Ultimately, his triumphs were a direct result of Divine providence, as God protected him and granted him success in every campaign he undertook.
