2 Chronicles - Chapter 17

The Lord was with Jehoshaphat, because he followed the ways of his ancestor, King David.  We read about his army in this chapter, but we also read a more unusual thing for a king to do:

"In the third year of his reign he sent his officials Ben-Hail, Obadiah, Zechariah, Nethanel and Micaiah to teach in the towns of Judah. With them were certain Levites—Shemaiah, Nethaniah, Zebadiah, Asahel, Shemiramoth, Jehonathan, Adonijah, Tobijah and Tob-Adonijah—and the priests Elishama and Jehoram. They taught throughout Judah, taking with them the Book of the Law of the Lord; they went around to all the towns of Judah and taught the people."

He sent certain selected people to travel throughout his country, taking the word of God with them.

Another King, a descendant of David, did the same thing in the New Testament. In Luke 9:

"When Jesus had called the Twelve together, he gave them power and authority to drive out all demons and to cure diseases, and he sent them out to proclaim the kingdom of God and to heal the sick."

And in Luke 10:

"After this the Lord appointed seventy-two others and sent them two by two ahead of him to every town and place where he was about to go."
