20:1-14
We now see the good side of Jehoshaphat. A vast army from Moab and Ammon attacked Jehoshaphat. Jehoshaphat was alarmed, but reacted in the right way by enquiring of the Lord. He also proclaimed a fast for the nation and all Judah sought the Lord. The Spirit of the Lord came upon Jahaziel, who then spoke to the assembly.
20:15-30
The word encouraged Jehoshaphat not to be afraid. God told him to attack, and made him aware of the enemy's tactics. The Lord would win the victory. The Korahites stood up and praised the Lord. Jehoshaphat organised the army and plundered the enemy. They returned to Jerusalem full of joy because of the victory the Lord had given them, The fear of the Lord came upon the surrounding kingdom.
20:31-37
Jehoshaphat’s reign ended sadly. Having failed once by helping Ahab, and having been rebuked for it, he made an alliance with the wicked king Ahaziah of Israel. God sent a prophet to rebuke him, and his reign came to an end.
