Jehoshaphat was the son and successor of Asa, king of Judah.
After fortifying his kingdom against Israel he set himself to cleanse the land
of idolatry (1Ki 22:43), In the third year of his reign he sent out priests and
Levites over the land to instruct the people in the law (vv 7-9).
2Ch 17:3
Vv 3-6: The blessings which flowed upon the kingdom of Judah
are presented as a direct result of the faithfulness of Jehoshaphat.
Vv 8,9: This spiritual state was established and maintained by
public reading of Scripture. Levites went out to the people with the word of the
LORD, rather than requiring them to leave their homes and seek Him
out.
