Jehoiada the priest receives an extraordinary honor upon his passing, an honor typically reserved only for royalty. He is granted a royal burial in the City of David alongside the kings, a tribute to his remarkable leadership and his lasting impact on the nation [ביאור שטיינזלץ].
The primary approach among commentators is that Jehoiada is celebrated first for his political and national achievements. He rescued the Israelites from the rule of the wicked Athaliah. By securing the throne for a rightful king from the line of David, he successfully restored the monarchy to its proper place.
Beyond his national triumphs, Jehoiada is recognized for his deep dedication to God and His Temple. Spiritually, he guided the Israelites back to the true worship of God [מצודת דוד]. He also took direct action to physically restore the Temple, rebuilding its foundations and appointing the necessary officials to ensure the holy service could function properly once again [מצודת דוד, מלבי״ם, ביאור שטיינזלץ].
