2 Kings 23:14-16

14Josiah smashed the sacred stones and cut down the Asherah poles and covered the sites with human bones.

15Even the altar at Bethel, the high place made by Jeroboam son of Nebat, who had caused Israel to sin—even that altar and high place he demolished. He burned the high place and ground it to powder, and burned the Asherah pole also.

16Then Josiah looked around, and when he saw the tombs that were there on the hillside, he had the bones removed from them and burned on the altar to defile it, in accordance with the word of the Lord proclaimed by the man of God who foretold these things.
