2 Kings 3:9-12

9So the king of Israel set out with the king of Judah and the king of Edom. After a roundabout march of seven days, the army had no more water for themselves or for the animals with them.

10“What!” exclaimed the king of Israel. “Has the LORD called us three kings together only to deliver us into the hands of Moab?”

11But Jehoshaphat asked, “Is there no prophet of the LORD here, through whom we may inquire of the LORD ?” An officer of the king of Israel answered, “Elisha son of Shaphat is here. He used to pour water on the hands of Elijah. That is, he was Elijah’s personal servant. ”

12Jehoshaphat said, “The word of the LORD is with him.” So the king of Israel and Jehoshaphat and the king of Edom went down to him.
