A specific group of individuals gathered at the House of God for the express purpose of singing and leading musical praise [מצודת דוד]. Regarding the description of the event, the primary approach among commentators is that these musicians simply raised their voices and sang out loud [ביאור שטיינזלץ]. However, a different perspective suggests that the account does not actually describe the act of raising their voices, but rather lists the name of an additional individual who joined the group [מצודת דוד].
Leading this choir was a man named Jezrahiah. Commentators agree unanimously on his role, noting that his specific title designates him as the appointed official in charge of the singers. This concept of an appointed authority is similar to the overseers appointed in the book of Genesis, confirming his formal position as the director of the musical group [ר' סעדיה גאון].
