1 Kings 22:3, 4, 6

The king of Israel had said to his officials, “Don’t you know that Ramoth Gilead belongs to us and yet we are doing nothing to retake it from the king of Aram?”

So he asked Jehoshaphat, “Will you go with me to fight against Ramoth Gilead?” Jehoshaphat replied to the king of Israel, “I am as you are, my people as your people, my horses as your horses.”

So the king of Israel brought together the prophets—about four hundred men—and asked them, “Shall I go to war against Ramoth Gilead, or shall I refrain?” “Go,” they answered, “for the Lord will give it into the king’s hand.”
