'Inner' in the Bible

But you, when you pray, enter into your inner room, and having shut your door, pray to your Father who is in secret, and your Father who sees in secret will reward you openly.

If therefore they tell you, 'Behold, he is in the wilderness,' don't go out; 'Behold, he is in the inner rooms,' don't believe it.

Therefore whatever you have said in the darkness will be heard in the light. What you have spoken in the ear in the inner rooms will be proclaimed on the housetops.

who, having received such a command, threw them into the inner prison, and secured their feet in the stocks.
