דברי הימים ב, פרק ל״ה, פסוק ט״ז

The preparation and execution of the Passover sacrifices required immense coordination. On this particular day, the entire process of bringing the offerings was carried out with extraordinary precision and flawless organization. Every detail was managed with perfect order and careful preparation [מצודת דוד].

This remarkable level of organization was clearly visible in the two main parts of the daily service. The first part involved preparing the meat of the Passover sacrifice, which was meant to be eaten by the Israelites. The second part focused on the fats and internal organs, which were offered and burned on the altar exclusively for God [מלבי״ם].
