דברי הימים ב, פרק כ״ט, פסוק כ״ז

King Hezekiah initiates the sacred ceremony of the burnt offering, creating a moment of perfect harmony between the physical service of the sacrifices and the musical worship of the Levites. The very moment the sacrifice was lifted onto the altar marked the exact beginning of the song directed to God [מצודת דוד, מצודת ציון, ביאור שטיינזלץ].

This musical worship was a rich, combined effort. The Levites did not merely sing; they raised their voices while simultaneously playing musical instruments, joined by the priests who sounded the trumpets [רלב״ג]. The instruments accompanying this vocal praise were specifically those originally crafted by King David [מצודת דוד, ביאור שטיינזלץ].

The precise timing of this music reveals important details about how the service was conducted. The singing and playing flowed continuously from the very start of the burnt offering until the sacrifice was entirely consumed and the task was fully complete. Furthermore, the direct connection between the start of the music and the start of the sacrifice teaches that the Levites sang exclusively while the burnt offering itself was being presented. Once this specific offering was finished, the music ceased, and the Levites did not continue to sing during the grain offerings and liquid libations that followed [רלב״ג].
