'Pagan' in the Bible

If he pays no attention to them [refusing to listen and obey], tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile (unbeliever) and a tax collector.

For all the [pagan] nations of the world greedily seek these things; and your [heavenly] Father [already] knows that you need them.

For [godly] sorrow that is in accord with the will of God produces a repentance without regret, leading to salvation; but worldly sorrow [the hopeless sorrow of those who do not believe] produces death.
