2 Kings 23:28
Now the rest of the acts of Josiah, and all that he did, are they not written in the book of the chronicles of the kings of Judah? Now the rest of the acts of Josiah, and all that he did, are they not written in the book of the chronicles of the kings of Judah?
The verse closes the account of Josiah by directing readers to the book of the chronicles of the kings of Judah for the rest of his acts and all that he did. It belongs to the record and history of Judah's kings, within the larger historical account extending from Solomon's accession to the Babylonian Captivity. Within that account it falls in its final section covering the remaining kingdom of Judah after the ten tribes were swept away. The chapter reports a national revival: during repairs to the temple the forgotten book of the law was found and read to Josiah, its words awakened his conscience, and after hearing a warning of judgment for idolatry he led reforms. The recovered book of the law led the king and people to renew their covenant with God, remove idolatrous worship, and restore and keep the Passover according to Scripture.
After Huldah's counsel, Josiah had objects used in Baal and sun worship removed from the Lord's house and destroyed. He was a good, devoted, zealous and decided reformer, the last king of Jerusalem who obeyed the Lord's commandments and kept his statutes. His reformation was only temporal, for he could not stop the people's downward turn toward sun and Baal worship. Chapter 23 records his reformation as the fulfillment of the prophecy concerning Jeroboam given by the disobedient prophet recorded in 1 Kings 13.
His reign ended in 607 BC, when the keeping of Israel's release years and Jubilees ceased. His sad death was mourned by Jeremiah, and soon afterward Judah fell before Nebuchadnezzar.
