'Within' in the Bible

and a voice came out of heaven saying: “You are My beloved Son, in You I am well-pleased and delighted!”

Immediately the [Holy] Spirit forced Him out into the wilderness.

Immediately Jesus, being fully aware [of their hostility] and knowing in His spirit that they were thinking this, said to them, “Why are you debating and arguing about these things in your hearts?

For from within, [that is] out the heart of men, come base and malevolent thoughts and schemes, acts of sexual immorality, thefts, murders, adulteries,

All these evil things [schemes and desires] come from within and defile and dishonor the man.”

where their worm [that feeds on the dead] does not die, and the fire is not put out.
