2 Kings 23:14-16

14He broke the sacred pillars into pieces, cut down the Asherah poles, then filled their places with human bones.

15He even tore down the altar at Bethel and the high place that had been made by Jeroboam son of Nebat, who caused Israel to sin. He burned the high place, crushed it to dust, and burned the Asherah.

16As Josiah turned, he saw the tombs there on the mountain. He sent someone to take the bones out of the tombs, and he burned them on the altar. He defiled it according to the word of the Lord proclaimed by the man of God who proclaimed these things.
