2 Chronicles 34:1-7

Josiah was eight years old when he became king, and he reigned thirty-one years in Jerusalem. He did right in the sight of the LORD, and walked in the ways of his father David and did not turn aside to the right or to the left. For in the eighth year of his reign while he was still a youth, he began to seek the God of his father David; and in the twelfth year he began to purge Judah and Jerusalem of the high places, the Asherim, the carved images and the molten images. They tore down the altars of the Baals in his presence, and the incense altars that were high above them he chopped down; also the Asherim, the carved images and the molten images he broke in pieces and ground to powder and scattered it on the graves of those who had sacrificed to them. Then he burned the bones of the priests on their altars and purged Judah and Jerusalem. In the cities of Manasseh, Ephraim, Simeon, even as far as Naphtali, in their surrounding ruins, he also tore down the altars and beat the Asherim and the carved images into powder, and chopped down all the incense altars throughout the land of Israel. Then he returned to Jerusalem.
