2 Chronicles 35:14 (KJV)

And they removed the burnt offerings, that they might give according to the divisions of the families of the people, to offer unto the Lord, as it is written in the book of Moses. And so did they with the oxen.

And they roasted the passover with fire according to the ordinance: but the other holy offerings sod they in pots, and in caldrons, and in pans, and divided them speedily among all the people.

And afterward they made ready for themselves, and for the priests: because the priests the sons of Aaron were busied in offering of burnt offerings and the fat until night; therefore the Levites prepared for themselves, and for the priests the sons of Aaron.

And the singers the sons of Asaph were in their place, according to the commandment of David, and Asaph, and Heman, and Jeduthun the king’s seer; and the porters waited at every gate; they might not depart from their service; for their brethren the Levites prepared for them.

So all the service of the Lord was prepared the same day, to keep the passover, and to offer burnt offerings upon the altar of the Lord, according to the commandment of king Josiah.
