I Corinthians 5:11-13

¹¹But 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. ¹²For what have I to do with judging outsiders? Do you not judge those who are within the church? ¹³But those who are outside, God judges. Remove the wicked man from among yourselves.
