דברי הימים ב, פרק ח׳, פסוק ט״ו

The smooth operation of the Temple relied heavily on strict organization and the unwavering dedication of those appointed to serve. The Priests and Levites demonstrated absolute obedience to the guidelines established for them, managing the sacred services with perfect order and precision. They remained completely loyal, never straying from the king's instructions or showing any signs of rebellion against his authority [מלבי״ם]. Instead, they followed the royal commands exactly as they were given [רד״ק, ביאור שטיינזלץ].

This strict adherence to duty covered every single aspect of their appointed tasks. Whether it involved the general daily operations of the Temple or the highly specific responsibility of guarding and managing the treasuries, the Priests and Levites executed every detail of their orders without fail [מצודת דוד, ביאור שטיינזלץ].
