2 Kings 23:20-24

He slaughtered all the priests of the illegal worship sites on their altars and then burned human bones on them. He went back to Jerusalem.

The king ordered all the people to celebrate the Passover for the Lord their God as it is written in this Book of the Promise.

The Passover had never been celebrated like this during the time of the judges who governed Israel or during the entire time of the kings of Israel and Judah.

But in the eighteenth year of King Josiah’s reign, this Passover was celebrated in Jerusalem for the Lord.

Josiah also got rid of the mediums, psychics, family idols, other idols, and disgusting gods that could be seen in the land of Judah and in Jerusalem. He did this to confirm the words of the Teachings written in the book that the priest Hilkiah found in the Lord’s temple.
