נחמיה, פרק י״ב, פסוק מ״א

The public gathering was brought to life by the active participation of its spiritual leaders. A dedicated group of priests—Eliakim, Maaseiah, Miniamin, Micaiah, Elioenai, Zechariah, and Hananiah—stepped forward to take on a central role. These specific men were the ones who physically sounded the trumpets during the event [מצודת דוד, ביאור שטיינזלץ].

Blowing these instruments was far more than a basic, formal duty. The priests sounded the trumpets to express an overwhelming sense of great joy, turning a standard ritual into a deeply emotional celebration [רש״י].
