Priestly duties weren't random; they followed a strict schedule. What does the 'order of his course' tell us about the structure of worship and its significance?
The phrase 'in the order of his course' points to a meticulously organized system of priestly service established by King David, recorded in 1 Chronicles 24. There were twenty-four divisions, or 'courses,' of priests, and each course served for a week at a time. This rotation ensured that the Temple duties were consistently carried out without overwhelming any single family. For Zacharias, it meant his turn to serve in this sacred capacity had arrived. This structured service allowed for continuity and prevented any one group from monopolizing the sacred rites. It also meant that for many priests, especially during the later periods of the Temple, the opportunity to perform certain high-profile duties, like burning the incense, might happen only once in a lifetime.
