1 Kings 22:30

Now Ahab's fear shows itself. Despite the unanimous prophecies of victory, despite his dismissal of Micaiah as merely contrary, Ahab's actions betray a man who is not truly confident. He says to Jehoshaphat: 'I will disguise myself and enter the battle, but you wear your robes.' In other words, let yourself be recognized as a king. Let the Syrian army see your royal garments and think you are the true target. Meanwhile, I will dress as an ordinary soldier and hide in the crowd. It is a coward's strategy dressed in the language of military wisdom. Ahab knows that the Syrians specifically seek the king of Israel. And so he means to let his ally's reputation shield him while he survives. The prophet has warned him truthfully, and his response is deception.

There is a bitter irony in this moment. Ahab takes the very precaution that, moments before, he swore was unnecessary. The 400 prophets guaranteed victory. But Ahab's hands are already reaching for his disguise. He speaks to Jehoshaphat as though the plan is simply military strategy, but we hear in it the voice of a man who does not actually believe the word of his prophets. And so Ahab enters the battle in disguise, thinking by his own cunning to escape the fate Micaiah has shown him.
