2 Kings 23:15-20

Moreover the altar that was at Beth-el, and the high place which Jeroboam the son of Nebat, who made Israel to sin, had made, even that altar and the high place he brake down; and he burned the high place and beat it to dust, and burned the Asherah. And as Josiah turned himself, he spied the sepulchres that were there in the mount; and he sent, and took the bones out of the sepulchres, and burned them upon the altar, and defiled it, according to the word of Jehovah which the man of God proclaimed, who proclaimed these things. Then he said, What monument is that which I see? And the men of the city told him, It is the sepulchre of the man of God, who came from Judah, and proclaimed these things that thou hast done against the altar of Beth-el. And he said, Let him be; let no man move his bones. So they let his bones alone, with the bones of the prophet that came out of Samaria. And all the houses also of the high places that were in the cities of Samaria, which the kings of Israel had made to provoke Jehovah to anger, Josiah took away, and did to them according to all the acts that he had done in Beth-el. And he slew all the priests of the high places that were there, upon the altars, and burned men’s bones upon them; and he returned to Jerusalem.
