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

12And 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 written in the book of Moses. And so with the oxen.
13And they roasted the passover with fire according to the ordinance: but the holy sod they in pots, and in caldrons, and in pans, and divided speedily among all the people.
14And afterward they made ready for themselves, and for the priests: because the priests the sons of Aaron in offering of burnt offerings and the fat until night; therefore the Levites prepared for themselves, and for the priests the sons of Aaron.
15And the singers the sons of Asaph in their place, according to the commandment of David, and Asaph, and Heman, and Jeduthun the king’s seer; and the porters at every gate; they might not depart from their service; for their brethren the Levites prepared for them.
16So 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.
17And the children of Israel that were present kept the passover at that time, and the feast of unleavened bread seven days.
18And there was no passover like to that kept in Israel from the days of Samuel the prophet; neither did all the kings of Israel keep such a passover as Josiah kept, and the priests, and the Levites, and all Judah and Israel that were present, and the inhabitants of Jerusalem.
