1 Kings 22:25

And Micaiah said, Behold, thou shalt see in that day, when thou shalt go into an inner chamber to hide thyself.

Micaiah spoke these words as a prophet of the Lord in his warning to Ahab and Jehoshaphat. That warning was fulfilled when Israel's forces were scattered and Ahab died. What was meant in particular by going into an inner chamber to hide oneself is not explained.
