2 Kings 23:14, 16-20

And he broke in pieces the pillars and cut down the Asherim and filled their places with the bones of men.

And 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. Then 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.” And 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. And 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. And 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.
