New American Standard Bible (NASB)
1 Corinthians 5
9 I wrote you in my letter not to associate with immoral people;
10 I did not at all mean with the immoral people of this world, or with the covetous and swindlers, or with idolaters, for then you would have to go out of the world.
11 But actually, I wrote to you not to associate with any so-called brother if he is an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler-not even to eat with such a one.
12 For what have I to do with judging outsiders? Do you not judge those who are within the church?
13 But those who are outside, God judges. Remove the wicked man from among yourselves.
1 Corinthians 6
1 Does any one of you, when he has a case against his neighbor, dare to go to law before the unrighteous and not before the saints?
2 Or do you not know that the saints will judge the world? If the world is judged by you, are you not competent to constitute the smallest law courts?
3 Do you not know that we will judge angels? How much more matters of this life?
4 So if you have law courts dealing with matters of this life, do you appoint them as judges who are of no account in the church?
5 I say this to your shame. Is it so, that there is not among you one wise man who will be able to decide between his brethren,
6 but brother goes to law with brother, and that before unbelievers?
