Josiah

2 Chronicles 34:1-3 (NKJV)
Josiah was eight years old when he became king, and he reigned thirty-one years in Jerusalem. 2 And he did what was right in the sight of the Lord, and walked in the ways of his father David; he did not turn aside to the right hand or to the left. 3 For in the eighth year of his reign, while he was still young, 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 wooden images, the carved images, and the molded images.
