2 Kings 12:1-3

12:1 (12:2) In Jehu’s seventh year Jehoash became king; he reigned for forty years in Jerusalem. His mother was Zibiah, who was from Beer Sheba. 12:2 Throughout his lifetime Jehoash did what the Lord approved, just as Jehoiada the priest taught him. 12:3 But the high places were not eliminated; the people continued to offer sacrifices and burn incense on the high places.
