2 Chronicles 18:1-3, 5, 9-11

But even though Jehoshaphat was very rich and much honored, he made a marriage alliance with Ahab of Israel. Some time later he paid a visit to Ahab at Samaria. Ahab celebrated his visit with a feast—a huge barbecue with all the lamb and beef you could eat. But Ahab had a hidden agenda; he wanted Jehoshaphat’s support in attacking Ramoth Gilead. Then Ahab brought it into the open: “Will you join me in attacking Ramoth Gilead?” Jehoshaphat said, “You bet. I’m with you all the way; you can count on me and my troops.”

The king of Israel got the prophets together—all four hundred of them—and put the question to them: “Should I attack Ramoth Gilead or should I hold back?” “Go for it,” they said. “God will hand it over to the king.”

Meanwhile, the king of Israel and Jehoshaphat were seated on their thrones, dressed in their royal robes, resplendent in front of the Samaria city gates. All the prophets were staging a prophecy-performance for their benefit. Zedekiah son of Kenaanah had even made a set of iron horns, and brandishing them, called out, “GOD’s word! With these horns you’ll gore Aram until there’s nothing left of them!” All the prophets chimed in, “Yes! Go for Ramoth Gilead! An easy victory! GOD’s gift to the king!”
