Beware of dogs - Dogs in the east are mostly without masters; they wander at large in the streets and fields, and feed upon offals, and even upon corpses; compare 1-Kings 14:11; 1-Kings 16:4; 1-Kings 21:19. They are held as unclean, and to call one a dog is a much stronger expression of contempt there than with us; 1-Samuel 17:43; 2-Kings 8:13. The Jews called the pagan dogs, and the Muslims call Jews and Christians by the same name. The term dog also is used to denote a person that is shameless, impudent, malignant, snarling, dissatisfied, and contentious, and is evidently so employed here. It is possible that the language used here may have been derived from some custom of affixing a caution, on a house that was guarded by a dog, to persons approaching it. Lenfant remarks that at Rome it was common for a dog to lie chained before the door of a house, and that a notice was placed in sight, "Beware of the dog." The same notice I have seen in this city affixed to the kennel of dogs in front of a bank, that were appointed to guard it. The reference here is, doubtless, to Judaizing teachers, and the idea is, that they were contentious, troublesome, dissatisfied, and would produce disturbance. The strong language which the apostle uses here, shows the sense which he had of the danger arising from their influence. It may be observed, however, that the term dogs is used in ancient writings with great frequency, and even by the most grave speakers. It is employed by the most dignified characters in the Iliad (Boomfield), and the name was given to a whole class of Greek philosophers - the Cynics. It is used in one instance by the Saviour; Matthew 7:6. By the use of the term here, there can be no doubt that the apostle meant to express strong disapprobation of the character and course of the persons referred to, and to warn the Philippians in the most solemn manner against them.
Beware of evil workers - Referring, doubtless, to the same persons that he had characterized as dogs The reference is to Jewish teachers, whose doctrines and influence he regarded only as evil We do not know what was the nature of their teaching, but we may presume that it consisted much in urging the obligations of the Jewish rites and ceremonies; in speaking of the advantage of having been born Jews: and in urging a compliance with the law in order to justification before God. In this way their teachings tended to set aside the great doctrine of salvation by the merits of the Redeemer.
Beware of the concision - Referring, doubtless, also to the Jewish teachers. The word rendered "concision" - κατατομή katatomē - means properly a cutting off, a mutilation. It is used here contemptuously for the Jewish circumcision in contrast with the true circumcision. Robinson, Lexicon. It is not to be understood that Paul meant to throw contempt on circumcision as enjoined by God, and as practiced by the pious Jews of other times (compare Acts 16:3), but only as it was held by the false Judaizing teachers. As they held it, it was not the true circumcision. They made salvation to depend on it, instead of its being only a sign of the covenant with God. Such a doctrine, as they held it, was a mere cutting off of the flesh, without understanding anything of the true nature of the rite, and, hence, the unusual term by which he designates it. Perhaps, also, there may be included the idea that a doctrine so held would be in fact a cutting off of the soul; that is, that it tended to destruction. Their cutting and mangling the flesh might be regarded as an emblem of the manner in which their doctrine would cut and mangle the church - Doddridge. The meaning of the whole is, that they did not understand the true nature of the doctrine of circumcision, but that with them it was a mere cutting of the flesh, and tended to destroy the church.

Beware of dogs - The Jews, who have here the same appellative which they formerly gave to the Gentiles: because the Gentiles were not included in the covenant, they called them Dogs; and themselves, the children of the Most High. Now, they are cast out of the covenant and the Gentiles taken in; therefore they are the dogs, and the Gentiles the children.
Evil workers - Judaizing teachers, who endeavored to pervert the Gospel.
The concision - Κατατομην· The cutting or excision; not περιτομην, the circumcision: the word is used by the apostle to degrade the pretensions which the Jews made to sanctity by the cutting in their flesh. Circumcision was an honorable thing, for it was a sign of the covenant; but as they now had rejected the new covenant, their circumcision was rendered uncircumcision, and is termed a cutting, by way of degradation.

Beware of dogs, beware of evil workers, beware of the (b) concision.
(b) He alludes to circumcision; and while they were boasting in it, they broke apart the Church.

Beware of dogs,.... By whom are meant the "judaizing" teachers, who were for imposing the works and ceremonies of the law upon the Gentiles, as necessary to salvation; and they have the name retorted on them they used to give to the Gentiles; see Matthew 15:26; nor should they think it too severe, since the Jews themselves say (p),
"the face of that generation (in which the Messiah shall come) shall he, , "as the face of a dog".
The apostle calls them so, because they returned to Judaism, as the dog to its vomit, 2-Peter 2:22; and because of the uncleanness in which many of them lived, and the impudence they were guilty of in transforming themselves into the apostles of Christ, and putting themselves upon an equal foot with them; as also for their calumny and detraction, their wrangling with the apostles, snarling at their doctrines, and biting them with the devouring words of reproach and scandal: likewise, they may be styled dogs for their covetousness, being such greedy ones as in Isaiah 56:10, with feigned words making merchandise of men; and for their love of their, bellies, which they served, and not Christ, and made a god of, Philippians 3:19. Moreover, because they were without, as dogs are, Revelation 22:15; having gone out from the communion of the saints, because they were not of them; or if among them, yet not true members of Christ, nor of his mystical body; all which are so many arguments why the saints should beware of them, and why their persons, conversation, and doctrine should be avoided,
Beware of evil workers: meaning the same persons, who were deceitful workers, did the work of the Lord unfaithfully, walked in craftiness, and handled the word of God deceitfully, endeavoured to subvert the Gospel of Christ, and the faith of men in it; who worked from bad principles, and with evil views; and notwithstanding their large pretensions to good works, teaching that justification and salvation were by them, which notion the apostle tacitly refers to in this character; yet were of bad a character, and such as Christ will reject another day as workers of iniquity; a character they deservedly bear, if there was no other reason for it than their preaching the doctrine of salvation by men's own works of righteousness, and who, and their ministry, are by all means to be shunned,
Beware of the concision; the men of the circumcision, as the Arabic version renders it; they chose to be called so, but the apostle would not give them that name, but calls them the "concision"; or "the concision of the flesh", as the Syriac version renders it; referring either to the cuttings in the flesh, forbidden Leviticus 21:5; or to the circumcision of the flesh rather, which they valued themselves upon, and were for introducing among the Gentiles, whereby they made sad divisions, and cutting work among the churches; and were some of them at least "cut" off, as the Ethiopic version renders it, from the churches; and who, as much as in them lay, cut themselves off from Christ, and rendered him unprofitable to them; see Galatians 5:2.

Beware--Greek, "Have your eye on" so as to beware of. Contrast "mark," or "observe," namely, so as to follow Philippians 3:17.
dogs--Greek, "the dogs," namely, those impure persons "of whom I have told you often" (Philippians 3:18-19); "the abominable" (compare Revelation 21:8, with Revelation 22:15; Matthew 7:6; Titus 1:15-16): "dogs" in filthiness, unchastity, and snarling (Deuteronomy 23:18; Psalm 59:6, Psalm 59:14-15; 2-Peter 2:22): especially "enemies of the cross of Christ" (Philippians 3:18; Psalm 22:16, Psalm 22:20). The Jews regarded the Gentiles as "dogs" (Matthew 15:26); but by their own unbelief they have ceased to be the true Israel, and are become "dogs" (compare Isaiah 56:10-11).
evil workers-- (2-Corinthians 11:13), "deceitful workers." Not simply "evildoers" are meant, but men who "worked," indeed, ostensibly for the Gospel, but worked for evil: "serving not our Lord, but their own belly" (Philippians 3:19; compare Romans 16:18). Translate, "The evil workmen," that is, bad teachers (compare 2-Timothy 2:15).
concision--Circumcision had now lost its spiritual significance, and was now become to those who rested on it as any ground of justification, a senseless mutilation. Christians have the only true circumcision, namely, that of the heart; legalists have only "concision," that is, the cutting off of the flesh. To make "cuttings in the flesh" was expressly prohibited by the law (Leviticus 21:5): it was a Gentile-heathenish practice (1-Kings 18:28); yet this, writes Paul indignantly, is what these legalists are virtually doing in violation of the law. There is a remarkable gradation, says BIRKS [HorÃ&brvbr; ApostolicÃ&brvbr;] in Paul's language as to circumcision. In his first recorded discourse (Acts 13:39), circumcision is not named, but implied as included in the law of Moses which cannot justify. Six or seven years later, in the Epistle to Galatians (Galatians 3:3), the first Epistle in which it is named, its spiritual inefficiency is maintained against those Gentiles who, beginning in the Spirit, thought to be perfected in the flesh. Later, in Epistle to Romans (Romans 2:28-29), he goes farther, and claims the substance of it for every believer, assigning the shadow only of it to the unbelieving Jew. In Epistle to Colossians (Colossians 2:11; Colossians 3:11), still later, he expounds more fully the true circumcision as the exclusive privilege of the believer. Last of all here, the very name is denied to the legalist, and a term of reproach is substituted, "concision," or flesh-cutting. Once obligatory on all the covenant-people, then reduced to a mere national distinction, it was more and more associated in the apostle's experience with the open hostility of the Jews, and the perverse teaching of false brethren.

Beware of dogs. Those snarling and snapping like dogs. The Judaizing teachers, who so troubled the early churches, are meant. See Galatians, chapter 1.
Evil workers. So called because by their false teaching about the necessity of circumcision they wrought evil.
Of the concision. Applied to those who called themselves the circumcision. It means simply a "cutting," the class who were mutilated. It is contemptuous.
We are the circumcision. See notes on Romans 2:29 and Romans 4:12. The true circumcision is not in the flesh, but of the heart in the Spirit.

Beware of dogs - Unclean, unholy, rapacious men. The title which the Jews usually gave the gentiles, he returns upon themselves. The concision - Circumcision being now ceased, the apostle will not call them the circumcision, but coins a term on purpose, taken from a Greek word used by the LXX, Leviticus 21:5, for such a cutting as God had forbidden.
