'Inner chambers' in the Bible

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

If therefore they should say to you, Behold, he is in the wilderness, do not go forth. Behold, he is in the inner chambers, do not believe.

Therefore, as many things as ye have said in the darkness will be heard in the light, and what ye have spoken in the ear in the inner chambers will be proclaimed upon the housetops.
