'Inner' in the Bible

But thou, when thou prayest, enter into thine inner chamber, and having shut thy door, pray to thy Father who is in secret, and thy Father who seeth in secret shall recompense thee.

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.

who, having received such a charge, cast them into the inner prison, and made their feet fast in the stocks.
