2 Kings 22:1-2 ESV
Josiah was eight years old when he began to reign, and he reigned thirty-one years in Jerusalem. His mother’s name was Jedidah the daughter of Adaiah of Bozkath. And he did what was right in the eyes of the LORD and walked in all the way of David his father, and he did not turn aside to the right or to the left.
