2 Kings 23:16-20

16And as Josiah turned, he saw the tombs there on the mount. And he sent and took the bones out of the tombs and burned them on the altar and defiled it, according to the word of the LORD that the man of God proclaimed, who had predicted these things. 17Then he said, “What is that monument that I see?” And the men of the city told him, “It is the tomb of the man of God who came from Judah and predicted these things that you have done against the altar at Bethel.” 18And he said, “Let him be; let no man move his bones.” So they let his bones alone, with the bones of the prophet who came out of Samaria. 19And Josiah removed all the shrines also of the high places that were in the cities of Samaria, which kings of Israel had made, provoking the LORD to anger. He did to them according to all that he had done at Bethel. 20And he sacrificed all the priests of the high places who were there, on the altars, and burned human bones on them. Then he returned to Jerusalem.
