2 Kings 3:5-10

But when Ahab died, the king of Moab rebelled against the king of Israel. So King Jehoram marched out of Samaria at that time and mustered all Israel. And he went and sent word to Jehoshaphat king of Judah: “The king of Moab has rebelled against me. Will you go with me to battle against Moab?” And he said, “I will go. I am as you are, my people as your people, my horses as your horses.” Then he said, “By which way shall we march?” Jehoram answered, “By the way of the wilderness of Edom.” 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. Then the king of Israel said, “Alas! The LORD has called these three kings to give them into the hand of Moab.”
