2 Chronicles 18:29-33

And the king of Israel said to Jehoshaphat, “I will disguise myself and go into battle, but you put on your robes.” So the king of Israel disguised himself, and they went into battle.

Now the king of Aram had commanded the commanders of his chariots, saying, “Do not fight with the small or great, but only with the king of Israel.”

So when the commanders of the chariots saw Jehoshaphat, they said, “He is the king of Israel!” And they turned aside to fight against him. But Jehoshaphat cried out, and the Lord helped him, and God diverted them from him.

When the commanders of the chariots saw that it was not the king of Israel, they turned back from pursuing him.

Now one man drew his bow at random and struck the king of Israel in a joint of the armor. So he said to the driver of his chariot, “Turn around and take me out of the battle, for I am severely wounded.”
