דברי הימים ב, פרק ל״ה, פסוק י׳

The execution of the Temple service was an undertaking defined by perfect order and careful planning. Every aspect of the work was carried out properly, fully organized, and prepared well in advance.

Commentators explain that this high level of organization was visible in the clear division of roles within the Temple. The priests took their positions in their designated spots, with each specific group standing separately. At the same time, the Levites stood according to their defined shifts.

This strict arrangement, where each group stood alone in its proper place, was not accidental. It was carried out exactly as the king had explicitly commanded, ensuring the entire service functioned with complete precision.
