2 Kings 23:20-24

He killed all the priests of the high places that were there, on the altars, and burned men’s bones on them; and he returned to Jerusalem.

The king commanded all the people, saying, “Keep the Passover to Yahweh your God, as it is written in this book of the covenant.”

Surely there was not kept such a Passover from the days of the judges who judged Israel, nor in all the days of the kings of Israel, nor of the kings of Judah;

but in the eighteenth year of King Josiah, this Passover was kept to Yahweh in Jerusalem.

Moreover, Josiah removed those who had familiar spirits, the wizards, and the teraphim, and the idols, and all the abominations that were seen in the land of Judah and in Jerusalem, that he might confirm the words of the law which were written in the book that Hilkiah the priest found in Yahweh’s house.
