2 Kings 3:5-8

5However, 1when King Ahab died, the king of Moab broke with the 2king of Israel. 6So King Jehoram left Samaria for battle 3at that time and mustered all Israel. 7Then 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. 45Consider me yours, my people as your people, my horses as your horses.” 8Then he said, “Which way shall we go up?” And he 6answered, “The way of the wilderness of Edom.”
