In these words the apostle mentions the great duties,

I.Of brotherly love. This he exhorts them to increase in yet more and more. The exhortation is introduced, not with a compliment, but with a commendation, because they were remarkable in the exercise of it, which made it less needful that he should write to them about it, Th1 4:9. Thus by his good opinion of them he insinuated himself into their affections, and so made way for his exhortation to them. Note, We should take notice of that in others which is good, to their praise, that by so doing we may lay engagements upon them to abound therein more and more. Observe,

1.What it is that the apostle commends in them. It was not so much their own virtue as God's grace; yet he takes notice of the evidence they gave of the grace of God in them. (1.) It was God's grace that he took special notice of: that God had taught them this good lesson: You yourselves are taught of God to love one another, Th1 4:9. Whoever does that which is good is taught of God to do it, and God must have the glory. All who are savingly taught of God are taught this lesson, to love one another. This is the livery of Christ's family. Note also, The teaching of the Spirit exceeds the teaching of men; and, as no man should teach contrary to what God teaches, so none can teach so effectually as he teaches; and men's teaching is fain and useless unless God teach also. (2.) The Thessalonians gave good evidence of their being taught of God by their love to the brethren in all Macedonia, Th1 4:10. They not only loved those of their own city and society, or such as were near them and just of their own sentiments, but their love was extensive. And a true Christian's is so to all the saints, though distant from him in place, and differing from him in some opinions or practices of less moment.

2.The exhortation itself is to increase more and more in this great grace and duty of brotherly love, Th1 4:10. Though these Thessalonians had in some sense no need of an exhortation to brotherly love, as if it were wholly wanting, yet they must be exhorted to pray for more, and labour for more. There are none on this side heaven who love in perfection. Those who are eminent in this or any other grace have need of increase therein as well as of perseverance unto the end.

II.Of quietness and industry in their callings. Observe, 1. The apostle exhorts to these duties: that they should study to be quiet, Th1 4:11. It is the most desirable thing to have a calm and quiet temper, and to be of a peaceable and quiet behaviour. This tends much to our own and others' happiness; and Christians should study how to be quiet. We should be ambitious and industrious how to be calm and quiet in our minds, in patience to possess our own souls, and to be quiet towards others; or of a meek and mild, a gentle and peaceable disposition, not given to strife, contention, or division. Satan is very busy to disquiet us; and we have that in our own hearts that disposes us to be disquiet; therefore let us study to be quiet. It follows, Do your own business. When we go beyond this, we expose ourselves to a great deal of inquietude. Those who are busy-bodies, meddling in other men's matters, generally have but little quiet in their own minds and cause great disturbances among their neighbours; at least they seldom mind the other exhortation, to be diligent in their own calling, to work with their own hands; and yet this was what the apostle commanded them, and what is required of us also. Christianity does not discharge us from the work and duty of our particular callings, but teaches us to be diligent therein. 2. The exhortation is enforced with a double argument; namely, (1.) So we shall live creditably. Thus we shall walk honestly, or decently and creditably, towards those that are without, Th1 4:12. This will be to act as becomes the gospel, and will gain a good report from those that are strangers, yea, enemies to it. Note, It is a great ornament to religion when the professors of it are of meek and quiet spirits, diligent to do their own business, and not busy-bodies in other men's matters. (2.) We shall live comfortably, and have lack of nothing, Th1 4:12. People often by their slothfulness bring themselves into narrow circumstances, and reduce themselves to great straits, and are liable to many wants, when such as are diligent in their own business live comfortably and have lack of nothing. They are not burdensome to their friends, nor scandalous to strangers. They earn their own bread, and have the greatest pleasure in so doing.

That ye may walk honestly - Ευσχημονως· Becomingly, decently, respectably; as is consistent with the purity, holiness, gravity, and usefulness of your Christian calling.

Them that are without - The unconverted Gentiles and Jews. See this expression explained at large on Col 4:5.

That ye may have lack of nothing - That ye may be able to get your bread by honest labor, which God will ever bless; and be chargeable to no man. He that is dependent on another is necessarily in bondage; and he who is able to get his own bread by the sweat of his brow, should not be under obligation even to a king.

I do not recollect whether, in any other part of this work, I have given the following story from the Hatem Tai Nameh. Hatem Tai was an Arabian nobleman, who flourished some time before the Mahommedan era; he was reputed the most generous and liberal man in all the east. One day he slew one hundred camels, and made a feast, to which all the Arabian lords and all the peasantry in the district were invited. About the time of the feast he took a walk towards a neighboring wood, to see if he could find any person whom he might invite to partake of the entertainment which he had then provided. Walking along the skirt of the wood, he espied an old man coming out of it, laden with a burden of faggots; he accosted him and asked if he had not heard of the entertainment made that day by Hatem Tai. The old man answered in the affirmative. He asked him why he did not attend and partake with the rest. The old man answered: "He that is able to gain his bread even by collecting faggots in the wood, should not be beholden even to Hatem Tai." This is a noble saying, and has long been a rule of conduct to the writer of this note.

That ye may walk honestly,.... Decently, in good credit and reputation, providing things honest in the sight of all men, for themselves and families, and honestly paying every man his own; on which account it became them to mind their own business, and work at their trades; otherwise their walk and conversation would be scandalous, and not honest and honourable:

toward them that are without: the men of the world, who were without the church; see Co1 5:12 profane sinners, unconverted Gentiles, that were without Christ and hope, and God in the world, and were aliens and strangers; and yet care should be taken that no occasion be given to such to reproach the name of God, the ways of Christ, and the doctrines of the Gospel:

and that ye may have lack of nothing; but have wherewith to supply the necessaries of life, and give to them also that stand in need, which is more blessed and honourable than to receive; or might not need any such instruction and exhortation, or any reproof for sloth and idleness; or not stand in need of "any man", as the Syriac version renders it; of the help and assistance of any, of any of those that are without, which would be dishonourable; or of them that are within, of the church, which might be burdensome. The Vulgate Latin version renders it, "that ye may not desire anything of anyone"; as the slothful man covets greedily all the day long what is another's, and this desire kills him, Pro 21:25 he covets an evil covetousness, and craves in a scandalous way the bread of others; when it would be more honourable for him to work with quietness, and eat his own bread got by honest labour, and not be beholden to another.

honestly--in the Old English sense, "becomingly," as becomes your Christian profession; not bringing discredit on it in the eyes of the outer world, as if Christianity led to sloth and poverty (Rom 13:13; Pe1 2:12).

them . . . without--outside the Christian Church (Mar 4:11).

have lack of nothing--not have to beg from others for the supply of your wants (compare Eph 4:28). So far from needing to beg from others, we ought to work and get the means of supplying the need of others. Freedom from pecuniary embarrassment is to be desired by the Christian on account of the liberty which it bestows.
