(2 Chronicles 17) One better

Also in the third year of his reign [Jehoshaphat] sent his leaders, Ben-Hail, Obadiah, Zechariah, Nethanel, and Michaiah, to teach in the cities of Judah. So they taught in Judah, and  had  the Book of the Law of the Lord with them; they went throughout all the cities of Judah and taught the people.

Jehoshaphat did one better than his son Asa. He not only removed the high places, but he sent teachers throughout the land to instruct the people in the law of the Lord, that their hearts might be turned toward the true and living God, and away from false and dead idols.
