1 Corinthians 5:9-13

9I wrote to you in my letter not to mix together with sexually immoral people—

10not at all meaning the sexually immoral people of this world or the greedy or swindlers or idolaters, for then you would have to exit the world.

11But now I am writing to you not to mix together with anyone who is being called a brother if he is sexually immoral or greedy or an idolater or a slanderer or a drunkard or a swindler—not even to eat with such a fellow.

12For what business do I have judging outsiders? Don’t you judge those who are inside?

13But those who are outside, God judges. Put away the wicked fellow from among yourselves.
