דברי הימים ב, פרק כ״ח, פסוק ז׳

The devastating military defeat suffered by the Kingdom of Judah was not limited to the general army; it struck at the very heart of the royal leadership. A mighty warrior from the Kingdom of Ephraim named Zichri successfully targeted the highest-ranking military commanders and state leaders of Judah [ביאור שטיינזלץ].

The tragedy unfolded as a continuous, connected chain of high-profile losses [רש״י]. Among the dead was Maaseiah, the son of King Ahaz [רש״י]. The royal administration was left severely crippled, as the primary official appointed to manage the king's household was struck down [מצודת ציון, ביאור שטיינזלץ]. Alongside him fell the king's second-in-command, the most important and powerful figure in the government after the monarch himself [מצודת ציון].
