Josiah the King wanted to reform the quite corrupt and idolatrous practices of the royal court. He had survived the assassination of his father Amon, who is described as corrupt. But he found more than he bargained for. This is not the lectionary text, but it is the verses preceding it.
8 Now in the eighteenth year of his reign, when he had cleansed the land and the house, he sent Shaphan the son of Azaliah, and Maaseiah the governor of the city, and Joah the son of Joahaz, the recorder, to repair the house of the Lord his God. 9 They came to Hilkiah the high priest and gave him the money that had been brought into the house of God, which the Levites, the keepers of the threshold, had collected from Manasseh and Ephraim and from all the remnant of Israel and from all Judah and Benjamin and from the inhabitants of Jerusalem. 10 And they gave it to the workmen who were working in the house of the Lord. And the workmen who were working in the house of the Lord gave it for repairing and restoring the house. 11 They gave it to the carpenters and the builders to buy quarried stone, and timber for binders and beams for the buildings that the kings of Judah had let go to ruin. 12 And the men did the work faithfully. Over them were set Jahath and Obadiah the Levites, of the sons of Merari, and Zechariah and Meshullam, of the sons of the Kohathites, to have oversight. The Levites, all who were skillful with instruments of music, 13 were over the burden-bearers and directed all who did work in every kind of service, and some of the Levites were scribes and officials and gatekeepers.2 Chronicles 34: 8-33, ESV/
14 While they were bringing out the money that had been brought into the house of the Lord, Hilkiah the priest found the Book of the Law of the Lord given through[b] Moses. 15 Then Hilkiah answered and said to Shaphan the secretary, “I have found the Book of the Law in the house of the Lord.” And Hilkiah gave the book to Shaphan. 16 Shaphan brought the book to the king, and further reported to the king, “All that was committed to your servants they are doing. 17 They have emptied out the money that was found in the house of the Lord and have given it into the hand of the overseers and the workmen.” 18 Then Shaphan the secretary told the king, “Hilkiah the priest has given me a book.” And Shaphan read from it before the king.
19 And when the king heard the words of the Law, he tore his clothes. 20 And the king commanded Hilkiah, Ahikam the son of Shaphan, Abdon the son of Micah, Shaphan the secretary, and Asaiah the king's servant, saying, 21 “Go, inquire of the Lord for me and for those who are left in Israel and in Judah, concerning the words of the book that has been found. For great is the wrath of the Lord that is poured out on us, because our fathers have not kept the word of the Lord, to do according to all that is written in this book.”
At this point one of the prophetesses in the Bible appears. She was clearly known as such, because the court knew precisely who to go to. Josiah was quite aware that Israel had broken the covenant they had made, as Joshua and Moses had predicted.
22 So Hilkiah and those whom the king had told went to Huldah the prophetess, the wife of Shallum the son of Tokhath, the son of Hasrah, the keeper of the wardrobe (now she lived in Jerusalem in the Second Quarter); and they spoke to her regarding this. 23 She said to them, “Thus says the Lord, the God of Israel, ‘Tell the man who sent you to Me, 24 thus says the Lord, “Behold, I am bringing evil on this place and on its inhabitants, even all the curses written in the book which they have read in the presence of the king of Judah. 25 Because they have forsaken Me and have burned incense to other gods, that they might provoke Me to anger with all the works of their hands; therefore My wrath will be poured out on this place and it shall not be quenched.”’ 26 But to the king of Judah who sent you to inquire of the Lord, thus you will say to him, ‘Thus says the Lord God of Israel regarding the words which you have heard, 27 Because your heart was tender and you humbled yourself before God when you heard His words against this place and against its inhabitants, and because you humbled yourself before Me, tore your clothes and wept before Me, I truly have heard you,” declares the Lord. 28 Behold, I will gather you to your fathers and you shall be gathered to your grave in peace, so your eyes will not see all the evil which I will bring on this place and on its inhabitants.”’” And they brought back word to the king.2 Chronicles 34:22-33, NASB.
29 Then the king sent and gathered all the elders of Judah and Jerusalem. 30 The king went up to the house of the Lord and all the men of Judah, the inhabitants of Jerusalem, the priests, the Levites and all the people, from the greatest to the least; and he read in their hearing all the words of the book of the covenant which was found in the house of the Lord.
31 Then the king stood in his place and made a covenant before the Lord to walk after the Lord, and to keep His commandments and His testimonies and His statutes with all his heart and with all his soul, to perform the words of the covenant written in this book. 32 Moreover, he made all who were present in Jerusalem and Benjamin to stand with him. So the inhabitants of Jerusalem did according to the covenant of God, the God of their fathers. 33 Josiah removed all the abominations from all the lands belonging to the sons of Israel, and made all who were present in Israel to serve the Lord their God. Throughout his [c]lifetime they did not turn from following the Lord God of their fathers.
We need to consider this: we have more than Moses, and the book of Law is freely available. But it appears that much of our society has lost both faith and a sense of covenant.
Those who honour God, God will honour. We forget that at our peril.
