Now I beseech you, by the coming. It may indeed be read, as I have noted on the margin, concerning the coming, but it suits better to view it as an earnest entreaty, taken from the subject in hand, just as in 1-Corinthians 15:31, when discoursing as to the hope of a resurrection, he makes use of an oath by that glory which is to be hoped for by believers. And this has much more efficacy when he adjures believers by the coming of Christ, not to imagine rashly that his day is at hand, for he at the same time admonishes us not to think of it but with reverence and sobriety. For it is customary to adjure by those things which are regarded by us with reverence. The meaning therefore is, "As you set a high value on the coming of Christ, when he will gather us to himself, and will truly perfect that unity of the body which we cherish as yet only in part through means of faith, so I earnestly beseech you by his coming not to be too credulous, should any one affirm, on whatever pretext, that his day is at hand." As he had in his former Epistle adverted to some extent to the resurrection, it is possible that some fickle and fanatical persons took occasion from this to mark out a near and fixed day. For it is not likely that this error had taken its rise earlier among the Thessalonians. For Timothy, on returning thence, had informed Paul as to their entire condition, and as a prudent and experienced man had omitted nothing that was of importance. Now if Paul had received notice of it, he could not have been silent as to a matter of so great consequence. Thus I am of opinion, that when Paul's Epistle had been read, which contained a lively view of the resurrection, some that were disposed to indulge curiosity philosophized unseasonably as to the time of it. This, however, was an utterly ruinous fancy, [1] as were also other things of the same nature, which were afterwards disseminated, not without artifice on the part of Satan. For when any day is said to be near, if it does not quickly arrive, mankind being naturally impatient of longer delay, their spirits begin to languish, and that languishing is followed up shortly afterwards by despair. This, therefore, was Satan's subtlety: as he could not openly overturn the hope of a resurrection with the view of secretly undermining it, as if by pits underground, [2] he promised that the day of it would be near, and would soon arrive. Afterwards, too, he did not cease to contrive various things, with the view of effacing, by little and little, the belief of a resurrection from the minds of men, as he could not openly eradicate it. It is, indeed, a plausible thing to say that the day of our redemption is definitely fixed, and on this account it meets with applause on the part of the multitude, as we see that the dreams of Lactantius and the Chiliasts of old gave much delight, and yet they had no other tendency than that of overthrowing the hope of a resurrection. This was not the design of Lactantius, but Satan, in accordance with his subtlety, perverted his curiosity, and that of those like him, so as to leave nothing in religion definite or fixed, and even at the present day he does not cease to employ the same means. We now see how necessary Paul's admonition was, as but for this all religion would have been overturned among the Thessalonians under a specious pretext.

Now we beseech you, brethren, by the coming of our Lord Jesus Christ - The phrase "by the coming," is not here, as our translators seem to have supposed, a form of solemn adjuration. It is not common, if it ever occurs, in the Scriptures, to make a solemn adjuration in view of an event, and the connection here demands that we give to the phrase a different sense. It means, respecting his coming; and the idea of Paul is: "In regard to that great event of which I spoke to you in my former epistle - the coming of the Saviour - I beseech you not to be troubled, as if it were soon to happen. As his views had been misunderstood or misrepresented, he now proposes to show them that there was nothing in the true doctrine which should create alarm, as if he were about to appear.
And by our gathering together unto him - There is manifest allusion here to what is said in the First Epistle 1-Thessalonians 4:17, "then we shall be caught up together with them in the clouds;" and the meaning is: "in reference to our being gathered unto him, I beseech you not to be shaken in mind, as if that event were near."

We beseech you - by the coming of our Lord - It is evident that the Thessalonians, incited by deceived or false teachers, had taken a wrong meaning out of the words of the first epistle, 1-Thessalonians 4:15, etc., concerning the day of judgment; and were led then to conclude that that day was at hand; and this had produced great confusion in the Church: to correct this mistake, the apostle sent them this second letter, in which he shows that this day must be necessarily distant, because a great work is to be done previously to its appearing.
Of the day of general judgment he had spoken before, and said that it should come as a thief in the night, i.e. when not expected; but he did not attempt to fix the time, nor did he insinuate that it was either near at hand, or far off. Now, however, he shows that it must necessarily be far off, because of the great transactions which must take place before it can come.

Now (1) we beseech you, brethren, by the coming of our Lord Jesus Christ, and [by] our (a) gathering together unto him,
(1) The second part of the epistle, containing an excellent prophecy of the state of the Church, which will be from the apostles time to the latter day of judgment.
(a) If we think earnestly upon that unmeasurable glory which we will be partakers of with Christ, it will be an excellent remedy for us against wavering and impatience, so that neither the glistening of the world will allure us, nor the dreadful sight of the cross dismay us.

Now we beseech you, brethren,.... The apostle having finished his first design in this epistle, which was to encourage the saints to patience under sufferings, proceeds to another view he had in writing it, and that is, to set the doctrine of Christ's coming, as to the time of it, in its proper light; and this is occasioned by what he had said concerning it in the former epistle, which was either misunderstood or misrepresented; and as he addresses the saints with a very affectionate appellation as his "brethren", so by way of entreaty "beseeching", and yet in a very solemn manner:
by the coming of our Lord Jesus: which is to be understood not of the coming of Christ in the flesh, to procure the salvation of his people; nor of his coming in his kingdom and power to take vengeance on the Jewish nation, for their rejection of him as the Messiah; but of his coming to judge the quick and dead, than which nothing is more sure and certain, being affirmed by angels and men, by prophets and apostles, and by Christ himself, or more desirable by the saints; wherefore the apostle entreats them by it, that whereas they believed it, expected it, and wished for it, they would regard what he was about to say: so that the words, though an entreaty, are in the form of an adjuration; unless they should be rendered as in the Ethiopic version, as they may, "concerning the coming of our Lord Jesus Christ"; and so express subject matter of the discourse now entering upon, with what follows:
and by our gathering together unto him; which regards not the great gatherings of the people to Christ the true Shiloh upon his first coming, and the preaching of the Gospel to both Jews and Gentiles, when there were not only great flockings to hear it, but multitudes were converted by it; nor the greater gatherings there will be in the latter day, at the time of the conversion of the Jews, and when the fulness of the Gentiles shall be brought in; nor the conversion of particular persons, who are gathered in to Christ, and received by him one by one; nor the assembling of the saints together for public worship, in which sense the word is used in Hebrews 10:25 but the gathering together of all the saints at the last day, at the second coming of Christ; for he will come with ten thousand of his saints, yea, with all his saints, when their dead bodies shall be raised and reunited to their souls, and they with the living saints will be caught up into the air, to meet the Lord there and be ever with him; when they will make up, complete and perfect, the general assembly and church of the firstborn, whose names are written in heaven: this will be the gathering together of all the elect of God; and so the Arabic version reads, "the gathering of us all"; and which, as it is certain, is greatly to be desired; it will be a happy meeting and a glorious sight; by this the apostle entreats and adjures them to regard what follows.

If errors arise among Christians, we should set them right; and good men will be careful to suppress errors which rise from mistaking their words and actions. We have a cunning adversary, who watches to do mischief, and will promote errors, even by the words of Scripture. Whatever uncertainty we are in, or whatever mistakes may arise about the time of Christ's coming, that coming itself is certain. This has been the faith and hope of all Christians, in all ages of the church; it was the faith and hope of the Old Testament saints. All believers shall be gathered together to Christ, to be with him, and to be happy in his presence for ever. We should firmly believe the second coming of Christ; but there was danger lest the Thessalonians, being mistaken as to the time, should question the truth or certainty of the thing itself. False doctrines are like the winds that toss the water to and fro; and they unsettle the minds of men, which are as unstable as water. It is enough for us to know that our Lord will come, and will gather all his saints unto him. A reason why they should not expect the coming of Christ, as at hand, is given. There would be a general falling away first, such as would occasion the rise of antichrist, that man of sin. There have been great disputes who or what is intended by this man of sin and son of perdition. The man of sin not only practises wickedness, but also promotes and commands sin and wickedness in others; and is the son of perdition, because he is devoted to certain destruction, and is the instrument to destroy many others, both in soul and body. As God was in the temple of old, and worshipped there, and is in and with his church now; so the antichrist here mentioned, is a usurper of God's authority in the Christian church, who claims Divine honours.

CORRECTION OF THEIR ERROR AS TO CHRIST'S IMMEDIATE COMING. THE APOSTASY THAT MUST PRECEDE IT. EXHORTATION TO STEADFASTNESS, INTRODUCED WITH THANKSGIVING FOR THEIR ELECTION BY GOD. (2Th. 2:1-17)
Now--rather, "But"; marking the transition from his prayers for them to entreaties to them.
we beseech you--or "entreat you." He uses affectionate entreaty, rather than stern reproof, to win them over to the right view.
by--rather, "with respect to"; as the Greek for "of" (2-Corinthians 1:8).
our gathering together unto him--the consummating or final gathering together of the saints to Him at His coming, as announced, Matthew 24:31; 1-Thessalonians 4:17. The Greek noun is nowhere else found except in Hebrews 10:25, said of the assembling together of believers for congregational worship. Our instinctive fears of the judgment are dispelled by the thought of being gathered together UNTO HIM ("even as the hen gathereth her chickens under her wings"), which ensures our safety.

By the coming. Rather, concerning the coming. His importunity is respecting this and "the gathering of the saints."
That ye be not soon shaken in mind. Be not agitated, or in distress (troubled).
Neither by spirit. By some one who says he has a revelation of the Spirit.
Nor by word. Nor by one who claims to quote a word or letter from us. It is thought that a forged letter had been circulated to which Paul alludes. In the close of this Epistle he shows how his letters may be known to be genuine. Some suppose, however, that by "letter" he refers to an incorrect interpretation which was placed on his first letter.

Our gathering together to him - In the clouds.
