A festive procession moves forward, filled with music and celebration. Among the marchers is a dedicated group of companions accompanying Zechariah the priest [רש"י, מצודת דוד]. As these men walk, they fill the air with music, playing a variety of instruments [מצודת דוד].
This music carries deep historical significance. The instruments they play were originally introduced by King David, who created them for choir directors to use alongside the songs he wrote to express gratitude to God [רלב"ג]. As the group marches, they do not just play the instruments, but they also sing the ancient songs composed by King David himself [ביאור שטיינזלץ].
At the very front of this musical gathering walks Ezra the Scribe, guiding the musicians and leading the entire procession forward [ביאור שטיינזלץ].
