Back in 1 Kings, Jehoshaphat was in just the one chapter and only had one battle mentioned but this has so much more about him.
Jehoshaphat is introduced as Asa’s son and the new king upon his death. We did see him back in 1 Kings 22 but nothing so in depth as this chapter. We get some details on the type of leader he was, that he “walked in the earlier ways of his father David”, and even a troop count toward the end of the chapter.
This is where the story that we had seen in 1 Kings 22 actually picks up in this book. The prior account had made it sound like the alliance with Israel was because they had come from the same people, or maybe it was just my inputting that into the story, that happens. But this one makes it clear that they had a marriage alliance and that was why “I am as you are, my people as your people.”
The battle turns out the same as the previous account with Ahab dying but Jehoshaphat living.
This chapter covers some new ground with Jehoshaphat from 1 Kings. He goes back to Judah after the battle of the last chapter and a seer comes and tells him some things from God that prompts him to set judges again.
Continuing on with new accounts of Jehoshaphat’s life, there is news of a huge group of Moabites, Ammonites, and some Meunites coming up to do battle against Judah. Jehoshaphat immediately goes to God in prayer. He actually has all the people fast and go with him in prayer and they are told to stand firm against the group. Jehoshaphat even has a special section of people who were “to sing to the Lord and praise him in holy attire” and the opposing side basically turns on itself and they kill each other. The people then get to spend days pillaging the remains.
After this, there is that Jehoshaphat died after 25 years reigning in Jerusalem. Right before the end of the chapter, though, there’s a bit about some ships that made for the wrong reason and destroyed by God.
