2 Chronicles 34:3 ERV

[3] When Josiah was in his eighth year as king, he began to follow the God worshiped by David his ancestor. He was still young when he began to obey God. When he was in his twelfth year as king he began to destroy the high places, the Asherah poles, and idols that were carved and idols that were made from molds from Judah and Jerusalem.
