דברי הימים ב, פרק ל״ה, פסוק ט״ו

The Temple service during the Passover sacrifice operated with perfect order and continuous dedication. The complex spiritual and logistical event relied on each group of Levites fulfilling a specific role without interruption. The singers remained at their designated stations, performing the Psalms and praises originally established by David, Asaph, Heman, and Jeduthun [מצודת דוד]. Each of these royal singers was considered a seer, uniquely inspired by the Holy Spirit [רש"י, ביאור שטיינזלץ]. Because the singers were occupied with their music throughout the entire day, it becomes clear that the Levites sang even during the actual processing of the Passover sacrifices. This is a notable detail, as the original commands in the Torah only explicitly require the sounding of trumpets for burnt offerings and peace offerings [רלב"ג].

Alongside the singers, the gatekeepers maintained a constant watch, with each guard remaining strictly at his assigned gate. The commentators agree that neither the singers nor the gatekeepers had to pause their service to prepare their own personal Passover sacrifices. They were able to remain fully dedicated to their duties because their fellow Levites took care of the preparations. The Levites who were not assigned to singing or guarding prepared all the necessary Passover provisions for them, just as they did for the Priests and the rest of the people.
