2 Chronicles 34:2-3

34:2 He did what the Lord approved and followed in his ancestor David’s footsteps; he did not deviate to the right or the left.

34:3 In 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.
