1 Kings 22:30-31

And the king of Israel said unto Jehoshaphat, I will disguise myself, and enter into the battle; but put thou on thy robes. And the king of Israel disguised himself, and went into the battle. {I will...: or, when he was to disguise himself, and enter into the battle} But the king of Syria commanded his thirty and two captains that had rule over his chariots, saying, Fight neither with small nor great, save only with the king of Israel.
