2 Kings 3:7-11

Then he went and sent word to Jehoshaphat the king of Judah, saying, “The king of Moab has broken away from me. Will you go with me to fight against Moab?” And he said, “I will go up. Consider me yours, my people as your people, my horses as your horses.”

Then he said, “Which way shall we go up?” And he answered, “The way of the wilderness of Edom.”

So the king of Israel went with the king of Judah and the king of Edom, and they made a circuit of seven days’ journey. But there was no water for the army or for the cattle that followed them.

Then the king of Israel said, “It is hopeless! For the Lord has called these three kings to hand them over to Moab!”

But Jehoshaphat said, “Is there no prophet of the Lord here, that we may inquire of the Lord by him?” And one of the king of Israel’s servants answered and said, “Elisha the son of Shaphat is here, who used to pour water on the hands of Elijah.”
