2 Chronicles 35:12
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 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.
The preparations for Josiah's Passover included setting apart the burnt offerings and the oxen and distributing them among the family divisions of the people so they could offer them to the Lord according to the instructions written in the book of Moses. The burnt offerings were removed and set aside for this distribution by families, and the oxen were dealt with in the same manner. The laws governing these burnt offerings and other sacrifices were contained in the book of Moses and were presented to the Lord through this orderly division of the people.
Josiah's Passover was a greater revival of hope than Hezekiah's Passover and stood just before the people's final descent into idolatry and sin. Like Hezekiah's Passover, it was an occasion when God blessed His ancient people. Josiah was the last king of Jerusalem who obeyed the Lord's commandments and kept His statutes, and his reign ended in 607 B.C. After that time the release years and jubilees were no longer kept and could not be kept, because the kings, nobles, people, and land could not be redeemed.
The reference to the book of Moses shows that Moses wrote the ceremonial law governing burnt offerings and sacrifices in a book, distinct from the moral law of the Ten Commandments which God wrote on stone. This distinction between the book containing the sacrificial system and the stone containing the Ten Commandments is made clear by the way the offerings were ordered according to what was written. As part of Josiah's religious revival, this ordering of worship illustrates that renewed spiritual life leads to missionary effort.
