2 Kings 3:5-8

5But 1when Ahab died, the king of Moab rebelled against the king of Israel. 6And King Jehoram went out of Samaria 2at that time and mustered all Israel. 7Then he went and sent word to Jehoshaphat the king of Judah, saying, “The king of Moab has rebelled against me. Will you go with me to fight against Moab?” And he said, “I will go up; 3I am as you are, my people as your people, my horses as your horses.” 8He said, “Which way shall we go up?” And he 4answered, “The way of the wilderness of Edom.”
