2 Kings 12:1-3

1 In the seventh year of Jehu [king of Israel],[1] Jehoash became king [over Judah], and he reigned forty years in Jerusalem. His mother's name was Zibiah of Beersheba.

2 Jehoash did right in the sight of the LORD all his days in which Jehoiada the priest instructed him.

3 Only the high places were not removed; the people were still sacrificing and burning incense [to the LORD] on the high places [rather than at the temple].
