2 Chronicles 35:10-15

10When everything was ready for the Passover celebration, the priests and the Levites took their places, organized by their divisions, as the king had commanded.

11The Levites then slaughtered the Passover lambs and presented the blood to the priests, who sprinkled the blood on the altar while the Levites prepared the animals.

12They divided the burnt offerings among the people by their family groups, so they could offer them to the Lord as prescribed in the Book of Moses. They did the same with the cattle.

13Then they roasted the Passover lambs as prescribed; and they boiled the holy offerings in pots, kettles, and pans, and brought them out quickly so the people could eat them.

14Afterward the Levites prepared Passover offerings for themselves and for the priests—the descendants of Aaron—because the priests had been busy from morning till night offering the burnt offerings and the fat portions. The Levites took responsibility for all these preparations.

15The musicians, descendants of Asaph, were in their assigned places, following the commands that had been given by David, Asaph, Heman, and Jeduthun, the king’s seer. The gatekeepers guarded the gates and did not need to leave their posts of duty, for their Passover offerings were prepared for them by their fellow Levites.
