2 Kings 12:1-3

1 In the seventh year of Jehu, Jehoash began to reign, and he reigned forty years in Jerusalem. And his mother's name [was] Zibiah of Beersheba.

2 And Jehoash did [that which was] right in the sight of the LORD all the time that Jehoiada, the priest, instructed him.

3 But with all this, the high places were not taken away; the people still sacrificed and burnt incense in the high places.
