2 Kings 23:15-20

Further, the altar that was at Bethel, the high place which Jeroboam the son of Nebat, who made Israel sin, had made, even that altar and the high place he tore down. Then he demolished its stones, ground them to dust, and burned the Asherah. And as Josiah turned, he saw the graves that were there on the mountain, and he sent men and had the bones taken from the graves, and burned them on the altar and [thereby] desecrated it, in accordance with the word of the LORD which the man of God prophesied, who proclaimed these things [about this altar, naming Josiah before he was born]. [1 Kin 13:2-5] Then Josiah said, “What is this monument (gravestone) that I see?” 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 to the altar of Bethel.” He said, “Let him alone; let no one disturb his bones.” So they left his bones undisturbed, with the bones of the prophet who came from Samaria. [1 Kin 13:31, 32] Josiah also removed all the houses of the high places which were in the cities of Samaria, which the kings of Israel had made provoking the LORD [to anger]; and he did to them just as he had done [to those] in Bethel. All the priests of the high places who were there he slaughtered on the altars, and burned human bones on them [to desecrate the places forever]. Then he returned to Jerusalem.
