8 Therefore, let us keep the feast, not with old leaven, nor with leaven of vice and malice and wickedness, but with the unleavened [bread] of purity (nobility, honor) and sincerity and [unadulterated] truth. [Exod. 12:19; 13:7; Deut. 16:3.]
9 I wrote you in my [previous] letter not to associate [closely and habitually] with unchaste (impure) people–
10 Not [meaning of course that you must] altogether shun the immoral people of this world, or the greedy graspers and cheats and thieves or idolaters, since otherwise you would need to get out of the world and human society altogether!
11 But now I write to you not to associate with anyone who bears the name of [Christian] brother if he is known to be guilty of immorality or greed, or is an idolater [whose soul is devoted to any object that usurps the place of God], or is a person with a foul tongue [railing, abusing, reviling, slandering], or is a drunkard or a swindler or a robber. [No] you must not so much as eat with such a person.
12 What [business] of mine is it and what right have I to judge outsiders? Is it not those inside [the church] upon whom you are to pass disciplinary judgment [passing censuring sentence on them as the facts require]?
13 God alone sits in judgment on those who are outside. Drive out that wicked one from among you [expel him from your church].
