2 Kings 22:8

And the king went up to the house of Yahweh and all the men of Judah and all the inhabitants of Jerusalem with him, and the priests and the prophets and all the people, both small and great; and he read in their hearing all the words of the book of the covenant which was found in the house of Yahweh.

Moreover, the mediums and the spiritists and the teraphim and the idols and all the detestable things that were seen in the land of Judah and in Jerusalem, Josiah purged in order that he might establish the words of the law which were written in the book that Hilkiah the priest found in the house of Yahweh.

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 an official of the city, and Joah the son of Joahaz the recorder, to repair the house of Yahweh his God.
