1 Corinthians 5:11–12

11 But now I am writing to you not to associate with anyone nwho bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one. 12 For what have I to do with judging ooutsiders? pIs it not those inside the church2 whom you are to judge?
