דברי הימים ב, פרק ח׳, פסוק י״ג

The ancient sacrificial system operated on a precise and steady schedule, expanding outward from a daily routine to encompass the entire annual calendar. At its core was the daily practice, which included every ritual requirement needed for each specific day [מצודת דוד]. In particular, this involved the continual offerings brought every single day [ביאור שטיינזלץ]. These offerings were brought up and sacrificed to God on the altar, following the exact instructions given by Moses.

Beyond the daily routine, the timeline expanded to include all public sacrifices offered on this altar [מצודת דוד]. The schedule marked the passage of time through special offerings designated for the Sabbaths and the New Moons. Finally, the calendar reached its peak with the appointed times. These refer to the three major pilgrimage festivals celebrated throughout the year: the Festival of Unleavened Bread, the Festival of Weeks, and the Festival of Tabernacles [ביאור שטיינזלץ].
