2 Chronicles 34:3-4

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

4He ordered the altars of the Baals to be torn down, and broke the incense altars that were above them. He smashed the Asherah poles, idols and images, crushed them up and sprinkled the dust over the tombs of those who had sacrificed to them.
