'Inner' in the Bible

But you, when you pray, go into your inner room, close your door and pray to your Father who is in secret, and your Father who sees what is done in secret will reward you.

The good man, from his [inner] good treasure, brings out good things; and the evil man, from his [inner] evil treasure, brings out evil things.

So if they tell you, ‘Look, He’s in the wilderness!’ don’t go out; ‘Look, He’s in the inner rooms!’ do not believe it.
