Joram son of Ahab became king of Israel in Samaria in the eighteenth year of Jehoshaphat king of Judah, and he reigned twelve years.
He did evil in the eyes of the LORD, but not as his father and mother had done. He got rid of the sacred stone of Baal that his father had made.
Nevertheless he clung to the sins of Jeroboam son of Nebat, which he had caused Israel to commit; he did not turn away from them.
Now Mesha king of Moab raised sheep, and he had to pay the king of Israel a tribute of a hundred thousand lambs and the wool of a hundred thousand rams.
But after Ahab died, the king of Moab rebelled against the king of Israel.
So at that time King Joram set out from Samaria and mobilized all Israel.
He also sent this message to Jehoshaphat king of Judah: “The king of Moab has rebelled against me. Will you go with me to fight against Moab?” “I will go with you,” he replied. “I am as you are, my people as your people, my horses as your horses.”
“By what route shall we attack?” he asked. “Through the Desert of Edom,” he answered.
So the king of Israel set out with the king of Judah and the king of Edom. After a roundabout march of seven days, the army had no more water for themselves or for the animals with them.
