2 Kings 3:9-12

So the king of Israel went with the king of Judah and the king of Edom. After they had marched seven days, there was no more water for the army or for their animals that were with them. The king of Israel said, “This is terrible! The LORD has called us three kings together to hand us over to the Moabites!” But Jehoshaphat asked, “Is there a prophet of the LORD here? We can ask the LORD through him.” An officer of the king of Israel answered, “Elisha son of Shaphat is here. He was Elijah’s servant.” Jehoshaphat said, “He speaks the LORD’s truth.” So the king of Israel and Jehoshaphat and the king of Edom went down to see Elisha.
