מלכים ב, פרק י״ד, פסוק י׳

Military victory can easily blind a conqueror, planting a dangerous sense of superiority. A stern warning is directed at the king of Judah, exposing the profound danger of arrogance born from battlefield success and urging him to be satisfied with his recent achievements. The triumph over the Edomites is the direct source of the king's swelling pride. His heart has become filled with a lofty sense of self-importance [מצודת ציון], leading him to the mistaken belief that he can win yet another military campaign [ביאור שטיינזלץ, מצודת דוד].

There is, however, a deeper dimension to his previous success. The victory over Edom was actually rooted in an ancient event and ancestral merit, as the tribe of Judah was originally responsible for killing Esau, the forefather of the Edomites. Because of this history, the king of Judah possesses a unique strength against the descendants of Esau. Yet, this specific merit will afford him no protection in a war against the Israelites [חומת אנך].

The wise counsel offered to the king is to remain in his own domain and preserve his dignity. By avoiding further conflict and staying home, he can safely guard the honor he earned from defeating Edom [מצודת דוד, חומת אנך]. Conversely, if he stubbornly chooses to force a battle, he will find only disgrace and shame rather than glory [רלב״ג]. There is no reason to start a new quarrel [מצודת ציון] and intentionally invite disaster. Since the opposing forces are vastly superior [ביאור שטיינזלץ], such an unnecessary provocation will inevitably lead to the personal ruin of the king and the complete downfall of his people [מצודת דוד].
