2 Chronicles 35:10-15

10So the service was prepared, and the priests stood in their places, and the Levites in their divisions, according to the king’s command.

11And they slaughtered the Passover offerings; and the priests sprinkled the blood with their hands, while the Levites skinned the animals.

12Then they removed the burnt offerings that they might give them to the divisions of the fathers’ houses of the lay people, to offer to the Lord, as it is written in the Book of Moses. And so they did with the cattle.

13Also they roasted the Passover offerings with fire according to the ordinance; but the other holy offerings they boiled in pots, in caldrons, and in pans, and divided them quickly among all the lay people.

14Then afterward they prepared portions for themselves and for the priests, because the priests, the sons of Aaron, were busy in offering burnt offerings and fat until night; therefore the Levites prepared portions for themselves and for the priests, the sons of Aaron.

15And the singers, the sons of Asaph, were in their places, according to the command of David, Asaph, Heman, and Jeduthun the king’s seer. Also the gatekeepers were at each gate; they did not have to leave their position, because their brethren the Levites prepared portions for them.
