The Story From the Boy King to Megiddo
The two accounts, from Amon's death to the lament for Josiah.
Manasseh reigned fifty-five years and rebuilt the high places his father Hezekiah had torn down. His son Amon reigned two years and was killed by his own servants in his palace.
The people of the land killed the conspirators and made the eight-year-old Josiah king.
And he did what was right in the eyes of the LORD and walked in all the ways of his father David; he did not turn aside to the right or to the left.
The writer of Kings judges the boy king at the start of his reign.
2 Kings 22:2BSB
By Chronicles' reckoning the king turned to the God of David as a youth, eight years into the reign.
In the twelfth year he began to break down the altars of the Baals and the Asherah poles in Judah, and carried the work into Manasseh, Ephraim, Simeon and as far as Naphtali.
In the eighth year of his reign, while he was still young, Josiah began to seek the God of his father David, and in the twelfth year he began to cleanse Judah and Jerusalem of the high places, the Asherah poles, the carved idols, and the cast images.
Chronicles gives the two years before the book was found.
In the eighteenth year the king sent Shaphan to have the money in the temple counted and paid to the workmen.
The carpenters, builders and masons bought timber and dressed stone, and the king asked no account of them.
But they need not account for the money put into their hands, since they work with integrity.”
The repairs were trusted to men who worked honestly.
2 Kings 22:7BSB
Hilkiah gave the book to Shaphan the scribe, who read it to the king.
While they were bringing out the money that had been taken into the house of the LORD, Hilkiah the priest found the Book of the Law of the LORD written by Moses.
Chronicles alone names the book's writer.
The king sent the high priest and four of his officials to ask the LORD about the book.
So Hilkiah the priest, Ahikam, Achbor, Shaphan, and Asaiah went and spoke to Huldah the prophetess, the wife of Shallum son of Tikvah, the son of Harhas, the keeper of the wardrobe. She lived in Jerusalem, in the Second District.
The king's men took the book to a prophetess for the word of the LORD.
The king gathered the elders and all the people, small and great, and read the whole book to them in the temple.
So the king stood by the pillar and made a covenant before the LORD to follow the LORD and to keep His commandments, decrees, and statutes with all his heart and all his soul, and to carry out the words of this covenant that were written in this book. And all the people entered into the covenant.
The reading ended in a covenant the whole people took.
2 Kings 23:3BSB
Then the purge ran through the temple and out to the land. The articles made for Baal were burned in the Kidron fields, the idolatrous priests were removed, and the high places were desecrated from Geba to Beersheba.
He burned the chariots of the sun and pulled down the altars on the roof near the upper room of Ahaz.
He also desecrated Topheth in the Valley of Ben-hinnom so that no one could sacrifice his son or daughter in the fire to Molech.
The reform ended the burning of children in the Valley of Ben-hinnom.
Chronicles tells of the lambs given by the king and his officials, and of the Levites who served by their divisions.
No such Passover had been observed in Israel since the days of Samuel the prophet. None of the kings of Israel ever observed a Passover like the one that Josiah observed with the priests, the Levites, all Judah, the Israelites who were present, and the people of Jerusalem.
Chronicles says no king of Israel had kept a Passover like it.
Thirteen years after the Passover, Josiah went out to meet the army of Egypt.
Chronicles says the archers struck him and that he died after his servants brought him to Jerusalem.
At the end of Josiah’s reign, Pharaoh Neco king of Egypt marched up to help the king of Assyria at the Euphrates River. King Josiah went out to confront him, but Neco faced him and killed him at Megiddo.
Kings gives Josiah's death in one verse.
All Judah and Jerusalem mourned him, and Jeremiah lamented over him. His son Jehoahaz reigned three months and did evil, and Neco took him to Egypt.
Then Jeremiah lamented over Josiah, and to this day all the choirs of men and women sing laments over Josiah. They established them as a statute for Israel, and indeed they are written in the Book of Laments.
The laments for Josiah were still sung when Chronicles was written.
