II Kings 3:1-7

Now Jehoram the son of Ahab became king over Israel at Samaria in the eighteenth year of Jehoshaphat king of Judah, and reigned twelve years. And he did evil in the sight of the LORD, but not like his father and mother; for he put away the sacred pillar of Baal that his father had made. Nevertheless he persisted in the sins of Jeroboam the son of Nebat, who had made Israel sin; he did not depart from them. Now Mesha king of Moab was a sheepbreeder, and he regularly paid the king of Israel one hundred thousand lambs and the wool of one hundred thousand rams. But it happened, when Ahab died, that the king of Moab rebelled against the king of Israel. So King Jehoram went out of Samaria at that time and mustered all Israel. Then he went and sent to Jehoshaphat 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; I am as you are, my people as your people, my horses as your horses.”
