25 Micaiah said, "Behold, you will see on that day, when you go into an inner room to hide yourself."

Micaiah addresses himself not so much to Zedekiah's question, as to the main point which lies in dispute - which of them, namely, is a true prophet. "When the news, i. e., of Ahab's death, caused by his following thy counsels, reaches Samaria, and thou hast to hide thyself from the vengeance of Ahaziah or Jezebel, then, in that day, thou wilt know whether I or thou be the true prophet."
When thou shalt go into an inner chamber - It is probable that this refers to some Divine judgment which fell upon this deceiver. Hearing of the tragical result of the battle, he no doubt went into a secret place to hide himself from the resentment of Jezebel, and the Israelitish courtiers, and there it is probable he perished; but how, when, or where, is not mentioned.
And Micaiah said, behold, thou shalt see in the day when thou shalt go into an inner chamber to hide thyself. Who would either accompany Ahab to the battle, and, upon his being wounded, flee to the first place of secrecy for safety; or, upon the news of his defeat brought to Samaria, would betake himself to a private chamber for security, fearing the enemy would pursue to the very place; or else through fear of the populace, who would attribute the death of the king to the advice of him and the other prophets.
Hide thyself - Probably he went with Ahab to the battle, after which he was glad to shelter himself where he could.
