2 Chronicles 34:3-5

For in the eighth year of his reign, while he was yet young, he began to seek after the God of David his father; and in the twelfth year he began to purge Judah and Jerusalem from the high places, and the Asherim, and the graven images, and the molten images. And they brake down the altars of the Baalim in his presence; and the sun-images that were on high above them he hewed down; and the Asherim, and the graven images, and the molten images, he brake in pieces, and made dust of them, and strewed it upon the graves of them that had sacrificed unto them. And he burnt the bones of the priests upon their altars, and purged Judah and Jerusalem.
