2 Kings 23:20-24

And he slays all the priests of the high places who are there by the altars, and burns the bones of man on them, and turns back to Jerusalem.

And the king commands the whole of the people, saying, “Make a Passover to your God YHWH, as it is written on this scroll of the covenant.”

Surely there has not been made like this Passover from the days of the ones judging who judged Israel, even all the days of the kings of Israel, and of the kings of Judah;

but in the eighteenth year of King Josiah, this Passover has been made to YHWH in Jerusalem.

And also, those having familiar spirits, and the wizards, and the teraphim, and the idols, and all the abominations that were seen in the land of Judah, and in Jerusalem, Josiah has put away, in order to establish the words of the Law that are written on the scroll that Hilkiah the priest has found in the house of YHWH.
