2 Chronicles 18:28-32

28The king of Israel and King Jehoshaphat of Judah attacked Ramoth Gilead.

29The king of Israel said to Jehoshaphat, “I will disguise myself and then enter the battle; but you wear your royal attire.” So the king of Israel disguised himself and they entered the battle.

30Now the king of Syria had ordered his chariot commanders, “Do not fight common soldiers or high ranking officers; fight only the king of Israel!”

31When the chariot commanders saw Jehoshaphat, they said, “He must be the king of Israel!” So they turned and attacked him, but Jehoshaphat cried out. The Lord helped him; God lured them away from him.

32When the chariot commanders realized he was not the king of Israel, they turned away from him.
