2 Kings 23:17-21

Then he said, “What is this gravestone there that I see?” And the men of the city told him, “It is the grave of the man of God who came from Judah and proclaimed these things which you have done against the altar of Bethel.”

And he said, “Leave him alone; no one is to disturb his bones.” So they left his bones undisturbed with the bones of the prophet who came from Samaria.

Then Josiah also removed all the houses of the high places which were in the cities of Samaria, which the kings of Israel had constructed, provoking the Lord to anger; and he did to them just as he had done in Bethel.

And he slaughtered all the priests of the high places who were there on the altars, and burned human bones on them; then he returned to Jerusalem. Passover Reinstituted

Then the king commanded all the people, saying, “Celebrate the Passover to the Lord your God as it is written in this Book of the Covenant.”
