2 Chronicles 18:3, 5, 9

“Will you go with me to Ramoth-gilead?” King Ahab of Israel asked King Jehoshaphat of Judah. Jehoshaphat replied, “Why, of course! You and I are as one, and my troops are your troops. We will certainly join you in battle.”

So the king of Israel summoned the prophets, 400 of them, and asked them, “Should we go to war against Ramoth-gilead, or should I hold back?” They all replied, “Yes, go right ahead! God will give the king victory.”

King Ahab of Israel and King Jehoshaphat of Judah, dressed in their royal robes, were sitting on thrones at the threshing floor near the gate of Samaria. All of Ahab’s prophets were prophesying there in front of them.
