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 teach in the cities of Judah. To teach in the cities of Judah - "To teach the fear of the Lord in the cities of Judah." - Targum.
In these verses we find a remarkable account of an itinerant ministry established by Jehoshaphat; and in this work he employed three classes of men:
1. The princes.
2. The Levites.
3. The priests.
We may presume that the princes instructed the people in the nature of the civil law and constitution of the kingdom; the Levites instructed them in every thing that appertained to the temple service, and ritual law; and the priests instructed them in the nature and design of the religion they professed. Thus the nation became thoroughly instructed in their duty to God, to the king, and to each other. They became, therefore, as one man; and against a people thus united, on such principles, no enemy could be successful.
