2 Chronicles 17:7

Also in the third year of his reign he sent to his princes, [even] to Benhail, and to Obadiah, and to Zechariah, and to Nethaneel, and to Michaiah, to (d) teach in the cities of Judah.

(d) He knew it was in vain to profess religion, unless such were appointed who could instruct the people in the same, and had authority to put away all idolatry.
