'Within' in the Bible

Sin took advantage of this, and by means of the Commandment stirred up within me every kind of coveting; for apart from Law sin would be dead.

and now it is no longer I that do these things, but the sin which has its home within me does them.

But if I do that which I desire not to do, it can no longer be said that it is I who do it, but the sin which has its home within me does it.

but I discover within me a different Law at war with the Law of my understanding, and leading me captive to the Law which is everywhere at work in my body--the Law of sin.
