2 Chronicles 35:12

Conaniah also, and Shemaiah and Nethanel, his brothers, and Hashabiah, Jeiel, and Jozabad, the chiefs of the Levites, gave to the Levites for the Passover offerings five thousand small livestock and five hundred head of cattle.

So the service was prepared, and the priests stood in their place, and the Levites by their divisions, according to the king’s commandment.

They killed the Passover lambs, and the priests sprinkled the blood which they received from their hands, and the Levites skinned them.

They roasted the Passover with fire according to the ordinance. They boiled the holy offerings in pots, in cauldrons, and in pans, and carried them quickly to all the children of the people.

Afterward they prepared for themselves and for the priests, because the priests the sons of Aaron were busy with offering the burnt offerings and the fat until night. Therefore the Levites prepared for themselves and for the priests the sons of Aaron.

The singers, the sons of Asaph, were in their place, according to the commandment of David, Asaph, Heman, and Jeduthun the king’s seer; and the gatekeepers were at every gate. They didn’t need to depart from their service, because their brothers the Levites prepared for them.
