2 Kings 3:9-12

The king of Edom and his troops joined them, and all three armies traveled along a roundabout route through the wilderness for seven days. But there was no water for the men or their animals. “What should we do?” the king of Israel cried out. “The LORD has brought the three of us here to let the king of Moab defeat us.” But King Jehoshaphat of Judah asked, “Is there no prophet of the LORD with us? If there is, we can ask the LORD what to do through him.” One of King Joram’s officers replied, “Elisha son of Shaphat is here. He used to be Elijah’s personal assistant.” Jehoshaphat said, “Yes, the LORD speaks through him.” So the king of Israel, King Jehoshaphat of Judah, and the king of Edom went to consult with Elisha.
