And that no man overreach, nor circumvent his brother in business: because the Lord is the avenger of all these things, as we have told you before, and have testified.

“"That no man transgress, and wrong his brother in the matter." He has well said, "that no man transgress." To each man God has assigned a wife, he has set bounds to nature, that intercourse with one only: therefore intercourse with another is transgression, and the taking of more than belongs to one, and robbery; or rather it is more cruel than any robbery; for we grieve not so much, when our riches are carried off, as when marriage is invaded. Dost thou call him brother, and wrongest him, and that in things which are unlawful? Here he speaks concerning adultery, but above also concerning "all fornication." For since he was about to say, "That no man transgress and wrong his brother," Do not think, he says, that I say this only in the case of brethren; you must not have the wives of others at all, nor even women that have no husbands, and that are common. You must abstain from "all fornication"; "Because," he says, "the Lord is an avenger in all these things." He exhorted them first, he shamed them, saying, "even as the Gentiles." Then from reasonings he showed the impropriety of defrauding a brother. Afterwards he adds the principal thing; "Because," he says, "the Lord is an avenger in all these things, as also we forewarned you and testified." For we do not these things without being punished, neither do we enjoy so much pleasure, as we undergo punishment.”

“Above, the Apostle commended the faithful for their constancy in tribulations and other goods; here he admonishes them, for the future, to act well. And first he sets forth a general admonition; second he specifies, at "that you abstain." Concerning the first he does two things: first he sets forth his intention, second he assigns the reason for the admonition, at "that you may abound," etc. He says therefore: I have heard of your past goods, but for the future we ask, etc. He induces them, first, on his own part. And so he says "we ask." Ps. 121:6: "Ask the things that are for peace," etc. Likewise on Christ's part, and so he says "we beseech," etc. He beseeches, however, because they were perfect. 1 Tim. 5:1: "Do not rebuke an elder, but beseech him as a father." But what does he ask? "That just as," etc. The Apostle had taught them how they ought to walk in the common way of justice, which is through the commandments. Hence he says: "you have received," etc. Ps. 118:32: "the way of your commandments," etc. Likewise how they might please God in the way of counsels. Wis. 4:10: "Being pleasing to God, he was made beloved." Or how you should walk, namely through right action. Jn. 12:35: "Walk while you have the light." How you should please, namely through right intention. "So also you may walk" — that is, that you keep to the first doctrine, not withdrawing from it. Gal. 1:8: "But though we, or an angel from heaven, should preach to you besides that which we have preached to you, let him be anathema." The reason for the admonition is taken, first, from the fruit of keeping the admonition; second, from the admonition itself, at "for you know what," etc. He says therefore: although you are good, yet through the exercise of the commandments and counsels you will abound and progress. 2 Cor. 9:8: "God is able to make all grace abound in you." For charity is so great that there always remains that in which one may progress. Likewise, the things which you received from the admonition are honorable and useful. Ps. 18:8: "The law of the Lord is unspotted," etc. Prov. 6:23: "The commandment is a lamp, and the law a light, and the way of life." Therefore he says "what precepts" — that is, of what sort. And this received through the Lord Jesus, from him. 1 Cor. 11:23: "For I have received of the Lord that which also I delivered unto you," etc. Heb. 2:3: "which, since it had received its beginning to be declared through the Lord, from those who heard," etc. And these are these things. "This is the will of God, your sanctification" — as if he were to say: all the precepts of God are for this, that you may be holy. For holiness denotes cleanness and firmness. And all the precepts of God lead to these: that one be clean from evil, and firm in good. Rom. 12:2: "that you may prove what is the will of God" — namely, as explained through the precepts. Then, when he says "that you abstain," he admonishes in particular. And first he corrects them concerning certain disorders among them; second he urges them to the observance of good things, in chapter 5, at "concerning the times." Now there were three disorders among them: namely, of carnal vices as regards some, likewise of curiosity, likewise of sorrow over the dead; and therefore he treats of these. The second, at "but concerning charity." The third, at "we would not have you." Concerning the first he does two things: first he admonishes them to abstain from an immoderate appetite for carnal things; second he gives the reason, at "because the avenger." Again, the first is divided into two, because first he forbids lust; second, avarice. And he always joins these together, because each is concerned with a bodily object, although this is completed in spiritual delight. Likewise, first he teaches to beware of lust as regards one not one's own; second as regards one's own wife, at "that he may know." He says therefore "that you abstain from fornication." For it is the will of God to abstain from fornication; therefore it is a mortal sin, because it is against the precept and will of God. Tob. 4:13: "Keep yourself from all fornication." But also with respect to one's wife you should abstain honorably, so that each one may know how to possess his vessel — that is, his wife — "in sanctification," ceasing for a time, "and in honor, not in passion" — namely, so that passion should go before — "even as the Gentiles" — because this is the way of the Gentiles, to seek present delights, but not those of the future life. "In sanctification and honor," because here is the due use of marriage, which is for the good of offspring, or for rendering the debt, and thus it can be without sin; but sometimes it is a venial sin, if concupiscence is not carried beyond the bounds of marriage — namely when, although he has concupiscence, he would nevertheless not use it unless she were his wife. But when it is outside the bounds of marriage, mortal sin follows, and this is when, if she were not his wife, he would still use her, and more willingly with another. Heb. last [chapter], 4: "Let marriage be honorable, and the bed undefiled." "But fornicators and adulterers God will judge." 1 Pet. 3:7: "Husbands likewise dwelling with them according to knowledge, giving honor to the woman as to the weaker vessel, as to co-heirs of grace and life, that your prayers be not hindered." Then, when he says "and let no man," he forbids avarice. Hence he says "and let no man overreach" — that is, use violence by taking away another's goods through power. Jas. 2:6: "Do not the rich oppress you by might?" Nor circumvent by deceit. Jer. 5:27: "As a snare full of birds, so their houses are full of deceit." Then, when he says "because the avenger," etc., the reason for the admonition is given, which he first assigns from divine vengeance; second he shows this vengeance to be just, at "for he has not called." He says therefore: let us abstain from these things, because "the Lord is the avenger." Gal. 5:21: "I foretell you, as I have foretold you, that they who do such things shall not obtain the kingdom of God." For certainly he avenges justly, of which there is one reason from God calling, a second from the contrariety to the gift. If the Lord calls you to one thing, and you do the contrary, you are worthy of punishment. And therefore he says "for he has not called," etc. Eph. 1:4: "He chose us in him before the foundation of the world, that we should be holy and unspotted in his sight in charity." Rom. 8:30: "whom he called, them he also justified," etc. Therefore he says "therefore," etc.; as if to say: this is one special reason which I have stated. There is another reason, because these vices are contrary to the Spirit, who has been given to us. Hence, whoever does these things does injury to the Holy Spirit. Therefore he says "who also," etc. Heb. 10:28: "A man making void the law of Moses dies without any mercy, on the word of two or three witnesses; how much more, do you think, does he deserve worse punishments, who has trodden underfoot the Son of God, and has held the blood of the testament unclean in which he was sanctified, and has done despite to the Spirit of grace?" Then, when he says "but concerning charity," etc., he draws them back from idleness. Now it must be known that, as Jerome says in his letter to the Galatians, the Thessalonians were generous, and it was their custom for the rich to give much; and therefore the poor idly clung to their benefaction, not caring for labors, but running about through houses. And therefore first he commends the generosity of the givers; second he dissuades the idleness of the receivers, at "and that you give attention." He says therefore, first, that they do not need to be admonished to charity; second he admonishes that they progress in it, at "but we ask." He says therefore "but concerning the charity of brotherhood" — that is, that you love the brethren — "it is not necessary to write to you." Rom. 12:10: "Loving one another with the charity of brotherhood." Heb. last [chapter]: "Let the charity of brotherhood remain in you." And the reason is because "you yourselves have learned from God" — namely, the precept in the law. Lev. 19:18: "You shall love your friend as yourself." Likewise in the Gospel. Jn. 13:34: "A new commandment I give you, that you love one another," etc. Or, you have learned by interior instruction. Jn. 6:45: "Everyone who has heard from the Father, and has learned, comes to me," etc. And this he learns through the Holy Spirit. Then, when he says "but we ask," he exhorts them to progress in charity, saying: and because you have charity toward all, therefore we ask that you progress. And although others abuse it, you nevertheless should persist. Prov. 15:5: "In abundant justice virtue is greatest." Then, when he says "and that you give attention," he reproves the idle: first their restlessness; second he shows how they should repress it; third, why. He says therefore: "that you give attention, that you be quiet." Prov. 7:10: "talkative and wandering, impatient of quiet, nor able to remain in the house with her feet," etc. 2 Thess. 3:7: "We were not restless among you, neither did we eat any man's bread for nothing, but in labor and weariness, working night and day," etc. Repressing idleness by exercising business. Hence he says "and that you do your own business." Prov. 24:27: "Diligently work your field, that afterward you may build your house." He says, however, "your own" — but is it not the case that another's business is also to be done? And it seems that it is so. Rom. last [chapter]: "that you assist her in whatever business." I respond. It must be said that all things can be done in a disordered way, if they are done outside the order of reason — namely when someone conducts himself dishonestly — and in an ordered way, namely when the order of reason is kept, and in necessity, and this is commendable. "And that you work with your own hands" — that is, by working with your hands. Ecclus. 33:29: "Idleness has taught much evil," etc. Ezek. 16:49: "This was the iniquity of Sodom your sister: pride, fullness of bread, and abundance, and the idleness of her and of her daughters, and they did not reach out a hand to the needy and the poor," etc. And this is a precept for all those who do not have other means by which they can live lawfully; because it is a precept of nature that a man should sustain his body. 2 Thess. 3:10: "He who is not willing to work, let him not eat either." Of this there is a twofold reason. The first, on account of the example to others. Hence he says "that also honestly," etc. For unbelievers, seeing your manner of life so idle, detest you. 1 Tim. 3:7: "But he must have a good testimony from those who are outside," etc. The second reason, that you should not desire the things that are others'; hence it is said "and that you desire nothing of any man's." Prov. 21:25: "Desires kill the slothful." Eph. 4:28: "He who stole, let him now steal no more," etc. And therefore, if this restlessness is repressed, it results in good example, and in the repression of desire.”

“That no man go beyond, and defraud his brother in any matter,.... Or "in this matter", as the Syriac version. This is commonly understood of transgressing the bounds of justice and equity between men and men; and of cheating and defrauding in trade and business, by increasing or lessening the value and prices of goods by the buyer and seller, by not keeping to the bargain, contract, covenant, or sample, by false weights and measures, and by taking the advantage of the weakness and ignorance of men; all which is aggravated by dealing thus with a brother; see Co1 6:8 and this hint is thought the rather necessary, since Thessalonica was a place of great trade and business. But the matter, or business referred to, is not trade, but the subject of chastity or uncleanness the apostle is speaking of, both before and after; and the phrases used either design the act of adultery, coveting a brother's wife, and lying with her, and so a defrauding and wronging of him by defiling his bed; or rather sodomitical practices, an unnatural lust and desire in men after men, and copulation with them; for rendered, "go beyond", answers to , "to go upon", or "lie with", so often used in Jewish writings for lying with women, men, and beasts, in an unlawful way. Thus, for instance (y), "these are to be burned, , "he that lies with a woman", and her daughter, &c.'' And again (z), "these are to be beaten, , "he that lies with" his sister, or his father's sister, &c.'' And the word translated "defraud", signifies a greedy, insatiable, and unnatural lust and desire after a man, a brother, or the committing of sodomitical practices with greediness: see Eph 4:19 which abominable iniquities are dissuaded from by the following reasons, because that the Lord is the avenger of all such; or "with respect to all these things", as the Vulgate Latin and Syriac versions render it; or "for all these things", as the Arabic and Ethiopic versions; as fornication, adultery, lasciviousness, and all sorts of abominable uncleanness. The person that commits these things the Lord avenges, either in this life, by the hand of the civil magistrate, who is the minister of God, a revenger to execute wrath on him that does evil; or by a violent death, as in the case of Zimri and Cozbi, and twenty four thousand more at the same time; or by some awful judgment from heaven, as in the case of Sodom and Gomorrah; or in the world to come; for the law of God is made and lies against such persons; these living and dying in such sins God will judge, to whom vengeance belongs; these shall not inherit the kingdom of God, but have their part and portion in the lake which burns with fire and brimstone. As we have also forewarned you and testified; not by a former epistle, as if this was the second to them, and what follows the first, as Grotius thought; but they did this when they were in person with them, knowing that these abominable vices greatly prevailed in their city; therefore they bore their testimony against them, and exposed the evil of them, and warned them of the danger by them, so that they could not now plead ignorance. The Ethiopic version reads in the first person singular, "as I have before said unto you, and testified to you". (y) Misna Sanhedrim, c. 9. sect. 1. (z) Misna Maccot, c. 3. sect. 1.”

“That no man go beyond and defraud his brother - That no man should by any means endeavor to corrupt the wife of another, or to alienate her affections or fidelity from her husband; this I believe to be the apostle's meaning, though some understand it of covetousness, overreaching, tricking, cheating, and cozenage in general. The Lord is the avenger of all such - He takes up the cause of the injured husband wherever the case has not been detected by man, and all such vices he will signally punish. Every species of uncleanness was practised among the heathens, nor were they reputed as vices. Their gods, their emperors, their philosophers, and their great men in general, gave them examples of every species of impurity; and they had no system of ethics which forbade these abominations. The Christian religion not only discountenances these things, but forbids them on the most awful penalties; therefore wherever Christianity prevails, these vices, if practised at all, are obliged to seek the deepest gloom of midnight to cover them from the eyes of men. On this account they are comparatively rare, even among the mere professors of Christianity; they exist, but do not flourish.”

“That no man overreach, nor deceive his brother in business. [1] The Protestant and Mr. N. even in their translations, add, in any matter, because some expound it of frauds and circumventions in any kind of business. But this addition of any, should be left out, seeing the best interpreters expound it of a prohibition of adultery, and the injury thereby done to another, and of sins of that kind only, which is confirmed by what follows and what goes before. See St. Jerome in chap. iv. ad Ephes. tom. 4. p. 369.; St. Chrysostom serm. 3 on this place. Here, says he, he speaks of adultery, as before of fornication, &c. See Theodoret, Theophylactus, Estius, Menochius, Cornelius a Lapide, &c. (Witham)”

“go beyond--transgress the bounds of rectitude in respect to his "brother." defraud--"overreach" [ALFORD]; "take advantage of" [EDMUNDS]. in any matter--rather as Greek, "in the matter"; a decorous expression for the matter now in question; the conjugal honor of his neighbor as a husband, Th1 4:4; Th1 4:7 also confirms this view; the word "brother" enhances the enormity of the crime. It is your brother whom you wrong (compare Pro 6:27-33). the Lord--the coming Judge (Th2 1:7-8). avenger--the Righter. of all such--Greek, "concerning all these things;" in all such cases of wrongs against a neighbor's conjugal honor. testified--Greek, "constantly testified [ALFORD].”
