Maintaining the daily operations of the Temple required a highly organized system of authority, funding, and oversight, all supported by official royal decrees. The singers of the Temple played a central role in this system, carrying out daily duties that were mandated by the king.
The identity of the commanding king and the nature of his orders offer different historical perspectives. One approach suggests that this refers to the Persian king, Darius. Under his authority, the Temple work was carried out, and he personally appointed the overseers based on his trust in them [רש״י, מצודת דוד, ביאור שטיינזלץ]. Another perspective identifies the king as King David, who originally established the organized shifts for future generations. In this view, the Persian king merely confirmed and upheld an ancient historical right [מלבי״ם].
The royal mandate itself carried a specific weight, understood in several ways. Most commentators view it as an official, binding commitment that gave the singers formal authority and validity [אבן עזרא, מצודת ציון, מצודת דוד, ביאור שטיינזלץ]. Others understand the appointment as a reflection of the deep faith and personal trust placed in these individuals [רלב״ג]. A third perspective connects the mandate directly to their craftsmanship and professional expertise [מלבי״ם].
The daily responsibilities of the singers were divided into two main areas. On an administrative and financial level, they were tasked with overseeing the physical maintenance and routine needs of the Temple. The king granted them full authority to draw funds directly from the royal treasury, trusting their daily reports regarding the exact expenses required for that day [רש״י, רלב״ג, מצודת דוד]. On a spiritual and ceremonial level, their role involved a fixed, daily commitment to the musical service itself. An expert in music was appointed to lead the singers, guiding them and deciding exactly which song and melody would be performed each day [ביאור שטיינזלץ, מלבי״ם].
