2 Chronicles 18
29 Ref And the king of Israel said to Jehoshaphat, I will make a change in my clothing, so that I do not seem to be the king, and will go into the fight; but do you put on your robes. So the king of Israel made a change in his dress, and they went to the fight.
30 Ref Now the king of Aram had given orders to the captains of his war-carriages, saying, Make no attack on small or great, but only on the king of Israel.
31 Ref So when the captains of the war-carriages saw Jehoshaphat, they said, It is the king of Israel. And turning about, they came round him, but Jehoshaphat gave a cry, and the Lord came to his help, and God sent them away from him.
32 Ref Now when the captains of the war-carriages saw that he was not the king of Israel, they went back from going after him.
