Melachim Alef 22:30-32

Orthodox Jewish Bible

³⁰ And the Melech Yisroel said unto Yehoshaphat, I will disguise myself, and enter into the milchamah; but put thou on thy robes. And the Melech Yisroel disguised himself, and went into the milchamah.

³¹ But HaMelech Aram commanded his 32 captains that had rule over his chariots, saying, Fight neither with katan nor gadol, save only with the Melech Yisroel.

³² And it came to pass, when the captains of the chariots saw Yehoshaphat, that they said, Surely it is the Melech Yisroel. And they turned aside to fight against him. Yehoshaphat cried out.
