2 Kings 23:14-16

14He smashed the sacred pillars to bits, cut down the Asherah pole, and filled those shrines with human bones.

15He also tore down the altar in Bethel at the high place made by Jeroboam son of Nebat, who encouraged Israel to sin. He burned all the combustible items at that high place and crushed them to dust; including the Asherah pole.

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.
