דברי הימים ב, פרק י״ח, פסוק כ״ד

Facing his opponent, Micaiah responds with absolute confidence about what is about to happen [ביאור שטיינזלץ]. He points to a future day of battle, warning that the false prophet will personally witness the harsh prophecy of doom coming true when King Ahab is killed in combat [רש״י, מצודת דוד].

Following the fulfillment of this true prophecy, the false prophet will be forced to flee and conceal himself deep within an inner room. There are two main explanations for what will drive him into hiding. One approach suggests he will run out of sheer terror, desperate to save his life from those seeking to kill him for causing the devastating national disaster [מצודת דוד]. Alternatively, his retreat will be driven by overwhelming shame. While he currently stands proud and certain of his own message, the looming military defeat will ultimately force him to run and hide in profound disgrace [ביאור שטיינזלץ].
