What does 2 Chronicles 35:11 mean?

His princes gave for a freewill offering to the people, to the priests, and to the Levites. Hilkiah, Zechariah, and Jehiel, the rulers of God’s house, gave to the priests for the Passover offerings two thousand six hundred small livestock, and three hundred head of cattle.

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 removed the burnt offerings, that they might give them according to the divisions of the fathers’ houses of the children of the people, to offer to Yahweh, as it is written in the book of Moses. They did the same with the cattle.

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.
