2 Chronicles 18:30-31

30 Now the king of Syria had commanded the captains of the chariots that were with him, saying, Fight ye not with small or great, save only with the king of Israel.

31 And it came to pass, when the captains of the chariots saw Jehoshaphat, that they said, It is the king of Israel. Therefore they compassed about him to fight: but Jehoshaphat cried out, and the LORD helped him; and God moved them to depart from him.
