2 Kings 22:1-2

1 Josiah was eight years old when he began to reign; and he reigned thirty-one years in Jerusalem: and his mother's name was Jedidah the daughter of Adaiah of Bozkath.  2 He did that which was right in the eyes of Yahweh, and walked in all the way of David his father, and didn't turn aside to the right hand or to the left.
