2 Kings 23:14-16

14He smashed the pillars and cut down the Asherah poles and filled their places with human bones.

15Moreover, the altar that was at Bethel and the shrine built by Jeroboam son of Nebat—who caused Israel to sin—that altar and the shrine he demolished, too. He burned the shrine and ground it to dust, and burned up the Asherah.

16Then, as Josiah looked around, he saw the burial caves there on the mountain, so he sent and took the bones out of the tombs and burned them on the altar, thus desecrating it—as was the word of Adonai which the man of God had proclaimed, who foretold it.
