1 Corinthians 5:11

But now have I written unto you,.... Which shows, that what he had written before was at another time, and in another epistle; but not that what he was now writing was different from the former, only he explains the persons of whom, and the thing about which he has before written:

not to keep company, if any man that is called a brother, be a fornicator; or if any man that is a brother is called, or named a fornicator; or covetous, or an idolater; or a railer, or a drunkard, or an extortioner, with such an one, no, not to eat. The apostle's meaning is, that in his prohibition of keeping company with men of the above character, he would be understood of such persons as were called brethren; who had been received into the church, and had been looked upon, and had professed themselves to be such; and who might be mentioned by name, as notoriously guilty of fornication, covetousness, idolatry, and extortion, mentioned in the former verse; to which are added two other sins any of them might be addicted to, as "railing" either at their fellow brethren and Christians, or others giving reproachful language to them, and fixing invidious characters on them: and "drunkenness"; living in the frequent commission of that sin, and others before spoken of; and that such persons remaining impenitent and incorrigible, still persisting, in such a vicious course of life, after due admonition given them, were not only to be removed from their religious society, from the communion of the church, and be debarred sitting down, and eating with them at the Lord's table, or at their love feasts, but also were to be denied civil conversation and familiarity with them, and even not suffered to eat common food at the same table with them: which though lawful to be used with the men of the world, yet for some reasons were not advisable to be used with such; partly for vindicating the honour of religion, and preventing the stumbling of the weak; and partly to make such offenders ashamed, and bring them to repentance. The apostle alludes to the behaviour of the Jews, either to persons that were under any pollution, as a woman in the days of her separation, when her husband לא יאכל עמה, "might not eat with her" off of the same plate, nor at the same table, nor on the same cloth; nor might she drink with him, nor mix his cup for him; and the same was observed to persons that had issues on them o: or rather to such as were under נדוי, "the sentence of excommunication", and such an one was obliged to sit the distance of four cubits from others, and who might not eat nor drink with him; nor was he allowed to wash and shave himself, nor a sufficiency of food, nor any to sit with him within the space of four cubits, except those of his house p.
