2 Kings 3:9-12 (ESV)
9 So the king of Israel went with the king of Judah and the king of Edom. And when they had made a circuitous march of seven days, there was no water for the army or for the animals that followed them. 10 Then the king of Israel said, “Alas! The Lord has called these three kings to give them into the hand of Moab.” 11 And Jehoshaphat said, “Is there no prophet of the Lord here, through whom we may inquire of the Lord?” Then one of the king of Israel's servants answered, “Elisha the son of Shaphat is here, who poured water on the hands of Elijah.” 12 And Jehoshaphat 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.
