'Inner chambers' in the Bible

Then David gave to Solomon his son the pattern of the porch of the temple , and of the houses thereof, and of the treasuries thereof, and of the upper rooms thereof, and of the inner chambers thereof, and of the place of the mercy-seat;

If therefore they shall say unto you, Behold, he is in the wilderness; go not forth: Behold, he is in the inner chambers; believe it not.

Wherefore whatsoever ye have said in the darkness shall be heard in the light; and what ye have spoken in the ear in the inner chambers shall be proclaimed upon the housetops.
