2nd Chronicles 18:29

26 And say, By the king's order this man is to be put in prison, and given prison food till I come back in peace.

27 And Micaiah said, If you come back at all in peace, the Lord has not sent his word by me.

28 So the king of Israel and Jehoshaphat, the king of Judah, went up to Ramoth-gilead.

29 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 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 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 Now when the captains of the war-carriages saw that he was not the king of Israel, they went back from going after him.
