(13) Their insincerity is shown by the fact that they are not really careful to observe the Law. What they do is only to serve as a blind, that they may be able to point to your mutilated flesh as the visible sign of their success in gaining proselytes.

They themselves who are circumcised.--The expression in the Greek includes, not only those who were circumcised themselves, but also those who were for circumcising others.

Glory in your flesh.--Make a boast of getting this rite performed upon your bodies.

Verse 13. - For neither they themselves who are circumcised keep the Law (οὐδὲ γὰρ οἱ περιτεμνόμενοι αὐτοὶ νόμον φυλάσσουσιν); for neither do they who are being circumcised themselves keep the Law; or, for not even. they who are being circumcised, themselves keep the Law. It is doubtful whether the οὐδὲ accentuates the main idea of the clause (see note on Galatians 1:12), or only the single term, "they who are being circumcised," as in John 7:5 it accentuates "his brethren." "For;" pointing back to the words," only that," "for no other reason than that," of the previous verse. The apostle means, it is from no zeal for the Law itself that they do what they do, for they are at no pains to keep the Law; but only with the object of currying favour with the Jews. The present participle περιτευνόμενοι is the reading more generally accepted, though the perfect περιτετμημένοι has a competing amount of documentary authentication. The perfect is so much the easier reading to understand ("not even those who have actually been circumcised") as to be much more likely to be a correction displacing περιτεμνόμενοι than the converse hypothesis of the latter being a correction of the other borrowed from ver. 3. "They who are being circumcised" may be understood of a party, including those who first set the movement ageing, who were one after another undergoing the rite. Another turn is given to this participial phrase, as meaning "who are eager for circumcision," "who are all for being circumcised, the circumcision party." Bishop Lightfoot is in favour of this view, referring to "the apt quotation" from an apocryphal book, in which the phrase appears used in this very sense (see his note). It is a sense grammatically difficult to sustain from the usage of the New Testament; for ὁ διώκων of Galatians 1:23, which has been cited on its behalf, does not bear it out. But the passion of scorn with which the apostle writes make the supposed strain upon strict grammatical propriety not altogether improbable. "Themselves;" this is inserted with allusion to the zeal shown by those men, both the first promoters and those drawn in by them, in urging upon others the observance, not indeed of the whole Law, but of certain of its prescriptions. The verb φυλάσσω is used similarly in Romans 2:26; Acts 21:24. The sense seems founded upon the notion of watching the Law to see what it requires, as one is endeavouring to carry it out. The article is wanting before νόμον, though specifically denoting the Law of Moses, as in Romans 2:25, 27, and often. But desire to have you circumcised, that they may glory in your flesh (ἀλλὰ θέλουσιν ὑμᾶς περιτέμνεσθαι ἵνα ἐν τῇ ὑμετέρᾳ σαρκὶ καυχήσωνται); but they desire you to receive circumcision, that in your flesh they may have whereof to glory. The conjunction ἀλλὰ is used in its proper original sense, "instead of that." All that they want is that in their intercourse with the Jews they may have your circumcision to refer to as evidence of the high respect which they and you as influenced by them have for the Law. "See! so far from trampling upon the Law, we and these our brethren too are adopting the very badge of the servants of the Law." The word "flesh" is in this clause used in its strictly literal signification. The account which the apostle here gives of the motives actuating this particular section of Judaizing reactionaries was no doubt grounded on specific information which he had just received. But such information, both in respect to its general probability and to its grave importance, was doubtless corroborated to his own mind by large experience which he had had elsewhere among the Gentile Churches of the behaviour of unsteady and imperfectly instructed Gentile converts. In almost every important place where Gentiles were won to the faith, there were previously existing communities of Jews (Acts 15:21); and contact with these must have given rise to an endless diversity of relations both of attraction and of repulsion. Everywhere, from the very first, the contact of Christianity with Judaism gave birth to varying phases of Judaico-Christian-ism such as afterwards developed into monstrous forms of error. It was no new thing with the apostle that he should find himself called upon to check, on the part of weak or insincere brethren, a tendency to draw towards Judaism at the cost of not merely unseemly but even fundamentally fatal compliances. The peril was always very near, and had to be constantly watched and guarded against.

6:12-15 Proud, vain, and carnal hearts, are content with just so much religion as will help to keep up a fair show. But the apostle professes his own faith, hope, and joy; and that his principal glory was in the cross of Christ. By which is here meant, his sufferings and death on the cross, the doctrine of salvation by a crucified Redeemer. By Christ, or by the cross of Christ, the world is crucified to the believer, and he to the world. The more we consider the sufferings of the Redeemer from the world, the less likely shall we be to love the world. The apostle was as little affected by its charms, as a beholder would be by any thing which had been graceful in the face of a crucified person, when he beholds it blackened in the agonies of death. He was no more affected by the objects around him, than one who is expiring would be struck with any of the prospects his dying eyes might view from the cross on which he hung. And as to those who have truly believed in Christ Jesus, all things are counted as utterly worthless compared with him. There is a new creation; old things are passed away, and new views and dispositions are brought in under the regenerating influences of God the Holy Spirit. Believers are brought into a new world, and being created in Christ Jesus unto good works, are formed to a life of holiness. It is a change of mind and heart, whereby we are enabled to believe in the Lord Jesus, and to live to God; and where this inward, practical religion is wanting, outward professions, or names, will never stand in any stead.But neither they themselves that are circumcised,.... That is, the pleaders for, and preachers of circumcision, whether they themselves were actually circumcised, or not; it means those that were of the circumcision, on that side of the question, whether heartily or not:

keep the law; of circumcision, as persons may preach up that, which they themselves do not practise; as did the Pharisees, the predecessors of these men; or if they did keep the law, and submit to it, yet this might be done, not out of regard unto it, and zeal for it, but for some other end; as Simon Magus submitted to baptism, and others preached Christ of envy and contention, and not of good will; or if they did do it in obedience to the law, yet this was not keeping the whole law, which circumcision obliged to; and which, unless they did so keep it, would signify nothing; and this no man is capable of keeping perfectly, and consequently no righteousness, life, and salvation, can be had hereby: besides, though these men were so zealous for the lighter matters of the law, the rites and ceremonies of it, as circumcision, &c. they disregarded the weightier and more material parts of it, as judgment, mercy, and faith; these they kept not, nor attended to: and many of them lived very dissolute lives and conversations, at least secretly, if not openly; which abundantly proved that they were far from keeping the law; and that their pleading for it, and submitting to some of the rituals of it, were not out of pure love and strict regard to it, but for some other end:

but desire to have you circumcised, that they may glory in your flesh; that is, in the circumcision of it; or, as the Ethiopic version, "in your bodies". Their view in bringing persons to submit to circumcision was, that they might have occasion to glory among the Jews, and boast to them of the numbers of proselytes they brought, and of the service they did to Judaism, and so increase their fame and glory among them.
