29So the king of Israel and Jehoshaphat king of Judah went up to Ramoth-gilead.
30And the king of Israel said to Jehoshaphat, “I will disguise myself and go into battle, but you wear your royal robes.” So the king of Israel disguised himself and went into battle.
31Now the king of Aram had ordered his thirty-two chariot commanders, “Do not fight with anyone, small or great, except the king of Israel.”
32When the chariot commanders saw Jehoshaphat, they said, “Surely this is the king of Israel!” So they turned to fight against him, but Jehoshaphat cried out.
33And when the chariot commanders saw that he was not the king of Israel, they turned back from pursuing him.
