2 Kings 23:16-20

16When Josiah turned around, he saw the tombs there on the hill. So he ordered the bones from the tombs to be brought; he burned them on the altar and defiled it. This fulfilled the Lord’s announcement made by the prophet while Jeroboam stood by the altar during a festival. King Josiah turned and saw the grave of the prophet who had foretold this.

17He asked, “What is this grave marker I see?” The men from the city replied, “It’s the grave of the prophet who came from Judah and foretold these very things you have done to the altar of Bethel.”

18The king said, “Leave it alone! No one must touch his bones.” So they left his bones undisturbed, as well as the bones of the Israelite prophet buried beside him.

19Josiah also removed all the shrines on the high places in the cities of Samaria. The kings of Israel had made them and angered the Lord. He did to them what he had done to the high place in Bethel.

20He sacrificed all the priests of the high places on the altars located there, and burned human bones on them. Then he returned to Jerusalem.
