2 Chronicles 35:10-13

Preparations were complete for the service of worship; the priests took up their positions and the Levites were at their posts as instructed by the king. They killed the Passover lambs, and while the priests sprinkled the blood from the lambs, the Levites skinned them out. Then they set aside the Whole-Burnt-Offering for presentation to the family groupings of the people so that each group could offer it to GOD following the instructions in the Book of Moses. They did the same with the cattle. They roasted the Passover lamb according to the instructions and boiled the consecrated offerings in pots and kettles and pans and promptly served the people.
