2 Chronicles 34:3-5

3In the eighth year of his reign, while he was still young, he began to seek the God of his father David. In his twelfth year he began to purge Judah and Jerusalem of high places, Asherah poles and idols.

4Under his direction the altars of the Baals were torn down; he cut to pieces the incense altars that were above them, and smashed the Asherah poles and the idols. These he broke to pieces and scattered over the graves of those who had sacrificed to them.

5He burned the bones of the priests on their altars, and so he purged Judah and Jerusalem.
