Verse 2 threatened a loss: Christ will be of no benefit. Verse 3 states a gain the Galatians had not reckoned on — an obligation. Paul is not adding a second penalty but exposing the terms of the contract they are signing.

The force turns on four things:

1. μαρτύρομαι is oath-language, not conversational reporting. Paul puts himself in the position of a witness giving formal testimony.
2. παντὶ ἀνθρώπῳ περιτεμνομένῳ is distributive and unrestricted — no individual case is exempt, which is exactly what a man contemplating the step would want to believe.
3. ὀφειλέτης is a debt-word, from the commercial and legal register, not a moral abstraction. The circumcised man has taken on a liability.
4. ὅλον τὸν νόμον locates the liability’s extent. Circumcision is not a badge that can be worn on its own; it is entry into a legal order that comes as a unit.

The unstated premise — that no one in fact does the whole law — Paul has already argued at Gal 3:10 and does not repeat here. Verse 3 states only the terms; the reader supplies the outcome.

A distinct lemma from μαρτυρέω (‘testify, bear witness’), though the two overlap. μαρτύρομαι is middle-only and in Koine usage means to call to witness and hence to affirm solemnly, with the weight of an oath or a formal deposition behind it. BDAG gives ‘affirm, insist, implore’ and places the NT occurrences in the register of solemn asseveration.

Paul’s other uses fix the register: Acts 20:26 (μαρτύρομαι ὑμῖν ἐν τῇ σήμερον ἡμέρᾳ, disclaiming bloodguilt — the formula of a man clearing himself in a legal sense), Eph 4:17 (μαρτύρομαι ἐν κυρίῳ), 1 Thess 2:12. Every instance introduces something the speaker wants on the record.

Rendering ‘I declare’ or ‘I tell you’ is too flat; the verb is doing what ἴδε ἐγὼ Παῦλος λέγω did in v. 2, escalating the personal authority behind the statement. ‘I solemnly attest’ in the literal tier, ‘I testify’ in smooth English — both keep the courtroom register visible.

δέ here is continuative rather than adversative (§10 requires it be rendered, not dropped): v. 3 is not a correction of v. 2 but a further disclosure on the same subject. ‘And’ or ‘now’ carries it; ‘but’ manufactures an opposition.

πάλιν is the live question.

English ‘again’ preserves all three, which is why it is retained rather than resolved to ‘once more I remind you’ or ‘furthermore.’ The smooth tier’s ‘once more’ leans slightly toward the first reading without excluding the others.

παντί with an anarthrous singular noun is distributive (already fixed in the glossary): ‘every man,’ taken one at a time, not ‘all men’ as a bloc. The rhetorical point is that no individual exception survives — the man who thinks his own case is different is precisely who is addressed.

περιτεμνομένῳ is a present participle, morphologically middle or passive. The tense matters: not the already-circumcised (which would be the perfect περιτετμημένῳ) but the man in the act of receiving it, or on the point of doing so. This is the same distinction as ἐὰν περιτέμνησθε in v. 2 and matters for the pastoral situation: Paul is not indicting Jewish believers circumcised in infancy (himself included, Phil 3:5) but Gentiles taking the step now.

On ἀνθρώπῳ: the generic term for a human being, not ἀνήρ. Per §3 the referent here is necessarily male, so no gender question arises in the rendering; but note that Paul chose the generic word, which keeps the statement a principle about persons rather than a statement about masculinity.

From ὀφείλω, ‘owe.’ The base sense is the debtor of the ledger — the man who owes money and can be sued for it (Matt 18:24, of the servant owing ten thousand talents). By extension it covers any binding obligation, and Paul uses it that way twice in Romans (1:14, ‘I am under obligation to Greeks and barbarians’; 8:12, ‘we are debtors, not to the flesh’; cf. 15:27).

The legal-commercial register should not be sanded off. ‘He is obliged’ is accurate but abstract; ‘he is a debtor’ keeps the ledger visible, and the ledger matters because Galatians is running a sustained argument about what secures standing before God. A man who takes on circumcision has, in Paul’s framing, signed for the whole account.

The noun is anarthrous and predicate: qualitative, describing what kind of person he now is, not identifying him as a particular debtor.

Note the LXX-adjacent Jewish idiom: the rabbinic ḥayyāb (‘liable, obligated’) covers the same ground, and Paul may be reproducing a formula a Judaizing teacher would recognize — one becomes obligated to the commandments. If so, Paul is not contradicting his opponents on the point of law but agreeing with them and letting the agreement do the damage.

ὅλον stands before the article — predicate position — which in Greek gives it the sense ‘the law as a whole, in its entirety,’ rather than an attributive ‘the whole law’ picking out one law among several. The point is totality, not identification.

The article on νόμον is worth noticing against v. 4’s anarthrous ἐν νόμῳ. Where Paul argues about law as a regime or principle, he tends to drop the article (glossary: ‘under law,’ ‘out of law’); here he has the definite Torah in view as a bounded body of commandments, which is what makes ‘the whole’ of it a meaningful quantity.

ποιῆσαι is an epexegetical aorist infinitive completing ὀφειλέτης — the content of the debt. The aorist is complexive: the whole law taken as a single undertaking, not a rendering of habitual practice. ‘Do’ (per the standing ποιέω entry) is retained over ‘keep’ or ‘obey,’ which import different verbs; the LXX standard for עָשָׂה with commandments is ποιέω (Deut 27:26; 28:58; Lev 18:5), and Paul quoted the Deut 27:26 form at Gal 3:10 with ποιῆσαι αὐτά in the same construction.

That quotation is the hidden hinge of this verse. Gal 3:10 cites Deut 27:26 LXX: cursed is everyone who does not remain in all things written in the book of the law to do them (τοῦ ποιῆσαι αὐτά). Verse 3 restates the obligation without restating the curse — the Galatians are expected to remember.

Paul states the obligation and stops. He does not here assert that the obligation cannot be met, nor that the Galatians will fail it. That premise is supplied from Gal 3:10-12 and from the argument’s whole shape; it is not in this sentence.

This matters for translation because the temptation is to render the verse as though it contained its own conclusion — ‘he is bound to keep a law no one can keep.’ Per §6, the text is not shaded toward the reader’s expected outcome. The verse is a statement of terms.

Chrysostom (Hom. in Gal. 5) takes the verse as Paul’s demonstration that circumcision cannot be received piecemeal: the man who accepts it has bound himself to the entire legislation, and since he will not in fact observe it all, he stands condemned by the very law he sought as protection. Chrysostom reads πάλιν as marking a second and heavier testimony after v. 2.

Jerome (Comm. in Gal.) presses the same point and notes the debtor-language specifically: debitorem esse universae legis — the man has made himself liable for the whole, not a part.

The Vulgate renders testificor autem rursum omni homini circumcidenti se — ‘circumcising himself,’ explicitly adopting the middle reading of the participle. That is a reading and not evidence (§11), but it is early evidence of how the voice was construed.

The text is stable. NA28 prints μαρτύρομαι δὲ πάλιν παντὶ ἀνθρώπῳ περιτεμνομένῳ with no variant recorded in the main apparatus that affects sense.

Minor witnesses vary the word order of ὅλον τὸν νόμον and a few read ὀφειλέτης ἐστίν in transposed order; neither is exegetically consequential and neither is printed. There is no textual basis for reading a perfect participle (‘already circumcised’) in place of the present.
