Divrey Hayamim Bais 18:30-32

Orthodox Jewish Bible

³⁰ Now Melech Aram had commanded the commanders of the chariots that were with him, saying, Fight ye not with katon or gadol, only with the Melech Yisroel.

³¹ And it came to pass, when the commanders of the chariots saw Yehoshaphat, that they said, It is the Melech Yisroel. Therefore they surrounded him to fight, but Yehoshaphat cried out, and Hashem helped him; and Elohim moved them away from him.

³² For it came to pass, that, when the commanders of the chariots perceived that it was not Melech Yisroel, they turned back from pursuing him.
