2 Kings 23:18-22

Josiah replied, “Leave it alone. Don’t disturb his bones.” So they did not burn his bones or those of the old prophet from Samaria.

Then Josiah demolished all the buildings at the pagan shrines in the towns of Samaria, just as he had done at Bethel. They had been built by the various kings of Israel and had made the Lord very angry.

He executed the priests of the pagan shrines on their own altars, and he burned human bones on the altars to desecrate them. Finally, he returned to Jerusalem.Josiah Celebrates Passover

King Josiah then issued this order to all the people: “You must celebrate the Passover to the Lord your God, as required in this Book of the Covenant.”

There had not been a Passover celebration like that since the time when the judges ruled in Israel, nor throughout all the years of the kings of Israel and Judah.
