Now we command you, brothers, in the name of our Lord Jesus Christ, that you withdraw yourselves from every brother who walks in rebellion, and not after the tradition which they received from us.
 But clearly this gives an immense help to the understanding of the passage. The apostle appeals to the saints. It is not a question of teaching in this verse, but the apostle beseeches them by a certain powerful motive, which was still in their souls. He does not mean, "We beseech you concerning," as some conceive, but as our English version says, "by." It is a legitimate meaning of the preposition with words of entreaty. He uses the hope of being gathered to Christ at His coming as a motive why they should not listen to those misleading the saints. Now mark the character of this false teaching. It was not the excitement of hope, but of terror produced on the spirit. It caused them to shake, hindering them from a settled, holy, hearty waiting for Christ. The error occupied them with the terrors of some intervening trouble. The pretence was that all the afflictions they had been enduring were parts or signs of the well-known day of trouble, the day of the Lord. Not at all, says the apostle: the trouble of that day will befall the enemies, not the friends, of the Lord. As they knew that every believer loved His name, the notion propagated was wholly astray. It was morally false, as ignoring in the first place His unfailing and perfect love for them.
