2 Chronicles 17:7 (KJV)

Therefore the Lord stablished the kingdom in his hand; and all Judah brought to Jehoshaphat presents; and he had riches and honour in abundance.

And his heart was lifted up in the ways of the Lord: moreover he took away the high places and groves out of Judah.

Also in the third year of his reign he sent to his princes, even to Ben–hail, and to Obadiah, and to Zechariah, and to Nethaneel, and to Michaiah, to teach in the cities of Judah.

And with them he sent Levites, even Shemaiah, and Nethaniah, and Zebadiah, and Asahel, and Shemiramoth, and Jehonathan, and Adonijah, and Tobijah, and Tob–adonijah, Levites; and with them Elishama and Jehoram, priests.

And they taught in Judah, and had the book of the law of the Lord with them, and went about throughout all the cities of Judah, and taught the people.
