2 Chronicles 34:3-4

3In the eighth year of his reign, while he was still young, Josiah began to seek the God of his father David, and in the twelfth year he began to cleanse Judah and Jerusalem of the high places, the Asherah poles, the carved idols, and the cast images. 4Then in his presence the altars of the Baals were torn down, and he cut to pieces the incense altars that were above them. He shattered the Asherah poles, the carved idols, and the cast images, crushed them to dust, and scattered them over the graves of those who had sacrificed to them.
