2 Kings 12:1-3

In the seventh year of Jehu Jehoash began to reign; and forty years reigned he in Jerusalem. And his mother’s name was Zibiah of Beer-sheba.

And Jehoash did that which was right in the sight of the LORD all his days wherein Jehoiada the priest instructed him.

But the high places were not taken away: the people still sacrificed and burnt incense in the high places.
