Verse 4 is the positive counterpart to the diagnosis of v. 3. The man who supposes he is something when he is nothing deceives himself; the remedy is not less self-assessment but a different kind of it. Paul does not say stop appraising yourself — he says δοκιμαζέτω, run the assay, and run it on your own work rather than on the comparison with your neighbor.

The verse turns on a single contrast that the Greek marks twice: εἰς ἑαυτὸν μόνον against εἰς τὸν ἕτερον. What is at issue is not whether one may have a καύχημα but where the reference point of the boasting lies. Paul is dismantling the comparative economy in which one’s standing is a function of someone else’s showing — the same economy that produced the mutual provocation and envy of Gal 5:26 and the fleshly boasting of 6:13.

Three things require care in English. First, δοκιμάζω is assay-language and issues in a verdict, not a survey. Second, καύχημα is the ground or basis of boasting, not the act (καύχησις) — Paul is not straightforwardly commending self-congratulation, and the tone of the clause is genuinely contested. Third, εἰς + accusative here is referential rather than locative, and rendering it ‘in himself’ quietly turns a statement about reference-point into a statement about the interior life. The verse also sits under the shadow of v. 5, whose γάρ grounds it, and of vv. 1–2, whose burden-bearing it does not contradict.

δοκιμάζω is assay vocabulary: testing that issues in a verdict of approval (BDAG 1–2). The metallurgical background is live in the LXX (Prov 17:3; Ps 65:10 LXX; Zech 13:9), and the corpus policy already fixes the rendering test and approve / prove at Phil 1:10, with the requirement that it share an English root-domain with δοκιμή (‘tested worth,’ Phil 2:22) and δόκιμος.

Two features of the form matter. The third-person imperative cannot be rendered directly in English and takes the standard ‘let him’ periphrasis (per the corpus policy fixed at Phil 4:5); it must not be converted to a second-person ‘test your own work,’ which would erase Paul’s shift from direct address (ὑμεῖς οἱ πνευματικοί, v. 1) to the impersonal individuating construction he sustains through vv. 3–5 (τις … ἕκαστος … ἕκαστος).

The present aspect is durative: a standing practice of assay, not a single audit. This is not a one-off examination but the ongoing alternative to the comparison-habit Paul is displacing.

What δοκιμάζω is not: it is not neutral examination (that would be a bare ἐξετάζω or βλέπω), and it is not condemnation. The verb’s built-in orientation toward a verdict of approval is what makes the following clause about καύχημα intelligible — Paul assumes the assay may come out positive.

The corpus already fixes καύχημα as ground for boasting, distinguished from καύχησις (‘act of boasting’), on the basis of Phil 1:26 and 2:16, where Paul produces his converts as evidence at the judgment. The distinction is not absolutely rigid in Koine — Paul himself blurs it occasionally (Rom 4:2) — but it holds well enough in the Pauline corpus to be worth preserving, and the article here (τὸ καύχημα) points to a definite basis rather than to boasting as an activity.

The article is doing real work. Paul does not write ἕξει καύχημα (‘he will have grounds for boasting’) but τὸ καύχημα — the ground for boasting he has, whatever it turns out to be. On the more austere readings of the verse, this is not a promise that the assay will yield something worth boasting about; it is a specification of where whatever ground he has is to be located.

The καυχ- family runs through Galatians to its resolution: the agitators boast ἐν τῇ ὑμετέρᾳ σαρκί (6:13), and Paul boasts ἐν τῷ σταυρῷ (6:14). Verse 4 stands between the vice (5:26 κενόδοξοι) and the resolution, and the English must keep the same root at every point so the reader can follow the thread. The standing corpus decision on καυχάομαι applies: one English root across pejorative and legitimized uses, since Paul redirects the verb by changing its object rather than by switching words.

The two εἰς + accusative phrases are the hinge of the verse, and they must be rendered identically or the antithesis collapses.

The preposition is here referential — ‘with reference to, in relation to’ — not locative and not benefactive. This is a recognized Koine extension of the directional accusative (BDF), and the parallel structure (εἰς ἑαυτόν … εἰς τὸν ἕτερον) rules out a locative reading: one cannot have a boast inside another person.

μόνον attaches to ἑαυτόν, not to the verb: it is himself alone, not only will have. Its position immediately after ἑαυτόν and before the object confirms this. And οὐκ negates the prepositional phrase, not ἕξει — Paul is not saying the man will not have a boast, but that the boast will not be referred to the other person.

The corpus glossary fixes ἕτερος as other (the other party) — the counterpart over against oneself, as distinct from ἄλλος, which adds a further item of the same kind. Paul exploits this distinction openly at Gal 1:6–7 (ἕτερον εὐαγγέλιον, ὃ οὐκ ἔστιν ἄλλο), so where either word appears in this letter the choice is deliberate.

Here the article plus singular ἕτερος names the counterpart in a comparison: not ‘other people’ in general but the other one, the person against whom the comparison would otherwise be run. This is the same usage already fixed at Phil 2:4 (τὰ ἑτέρων, ‘the interests of others’), where the ἕτερος is the fellow member of the congregation.

Rendering ‘someone else’ or ‘others’ loses the singularity and with it the picture Paul has in view: two men, one measuring himself against the other. ‘The other party’ or ‘the other person’ keeps it. English idiom permits ‘his neighbor’ but that imports πλησίον, which Paul used at 5:14 and did not use here.

ἕκαστος is the distributive already fixed in the corpus as each one / each of you, individuating a plural addressee. Its placement here is worth marking: the Greek holds the subject back until after the verb, so the clause reads the work of himself let him test — each one.

This is not accidental. The same word opens v. 5 (ἕκαστος γὰρ τὸ ἴδιον φορτίον βαστάσει), and the pair frames the argument: each man assays his own work now; each man will carry his own load then. The distributive is Paul’s instrument for breaking the comparative frame — once the unit of assessment is the individual, there is no one to measure against.

Note also the shift in person across vv. 1–5. Paul begins with second-person plural address (ὑμεῖς οἱ πνευματικοί, καταρτίζετε), moves to second-person singular (σκοπῶν σεαυτόν, σὺ πειρασθῇς), then to the impersonal τις (v. 3) and ἕκαστος (vv. 4, 5). The English should not level this into uniform second-person exhortation; the third-person forms hold the ruling at arm’s length, which is part of its pastoral tact.

The reflexive occurs twice, in different cases: genitive ἑαυτοῦ (‘his own work’) and accusative ἑαυτόν (‘himself’). Together with ἑαυτόν in v. 3 (φρεναπατᾷ ἑαυτόν, ‘he deceives himself’) that makes three occurrences of the reflexive in two verses.

The repetition is the argument. Verse 3 diagnoses a man turned in on himself in the wrong way — self-deception. Verse 4 prescribes a man turned in on himself in the right way — self-assay. Paul is not commending self-absorption; he is insisting that the only self one is competent to audit is one’s own, and that the audit is what makes comparison unnecessary.

In the literal tier the genitive is kept as ‘of himself’ so the reflexive form stays visible; smooth registers render ‘his own,’ which is correct English for the construction. Note that Paul had αὐτοῦ available and wrote the reflexive.

Per §3, the masculine forms throughout stand as written. The referent in a congregation is certainly mixed (cf. Gal 3:28), and the masculine singular is the ordinary Greek default for a generic individual; it is footnoted rather than neutralized.

ἔργον here is singular and anarthrous-in-sense despite the article (τὸ ἔργον ἑαυτοῦ — the article is possessive-anaphoric with the reflexive). The corpus already fixes ἔργον in Philippians as labor / work in the sense of gospel labor rather than works in the soteriological sense (Phil 1:6, 22; 2:30).

The same holds here. In a letter that has spent five chapters denying that ἔργα νόμου justify (2:16; 3:2, 5, 10), Paul’s use of the singular ἔργον in a positive imperative is deliberate: this is not law-observance scored on a ledger but the individual’s own conduct and labor, the thing v. 5 will call τὸ ἴδιον φορτίον.

The fronting of τὸ ἔργον ἑαυτοῦ before the verb is topicalizing (per §4: emphatic word order preserved). English should keep the object early — ‘his own work let him test’ in the literal tier, and ‘test his own work’ in smooth registers where fronting is unavailable.

Do not gloss to ‘deeds’ (plural, and pulls toward the vice-catalogue register) or to ‘conduct’ (abstracts the concrete noun).

δέ is mildly adversative, marking the turn from the self-deceiver of v. 3 to the prescribed alternative. Per §10 the connective is rendered, not dropped: ‘but’ carries the contrast without overstating it.

The unusual feature of the clause is the word order: τὸ δὲ ἔργον ἑαυτοῦ δοκιμαζέτω ἕκαστος. Object fronted, verb, subject last. This is marked against the unmarked δοκιμαζέτω ἕκαστος τὸ ἔργον ἑαυτοῦ, and it puts the emphasis exactly where the argument needs it — on his own work as the thing to be assayed, over against the implied alternative of assaying someone else’s.

English can reproduce the fronting only awkwardly, but the literal tier should keep it visible. The smooth tier compensates by placing ‘his own’ in a stressed position within the object phrase.

The verse reads oddly against Paul’s usual treatment of boasting, and the scholarship is genuinely divided on its tone.

What is not in doubt is the target. Paul is attacking the comparative economy of honor — the same economy behind κενόδοξοι, ἀλλήλους προκαλούμενοι, ἀλλήλοις φθονοῦντες (5:26) and behind the agitators’ desire to boast ἐν τῇ ὑμετέρᾳ σαρκί (6:13). Comparison is the mechanism by which vainglory operates, and self-assay is what starves it.

The paragraph looks self-contradictory in English: bear one another’s burdens (v. 2) and then each will carry his own load (v. 5), with v. 4’s individualizing imperative in between and a γάρ in v. 5 grounding it.

The Greek marks a distinction the English tends to lose. βάρη (v. 2) are weights — the crushing kind, which is why they can be shared. φορτίον (v. 5) is the standard word for a pack, a ship’s cargo, a soldier’s kit: the load properly assigned to a bearer. The verb is the same (βαστάζω, already fixed in the corpus as bear / carry, with the note that Galatians runs a deliberate pattern across 5:10, 6:2, and 6:5), and keeping one English root at all three points lets the reader see the tension rather than having it smoothed away.

So the sequence runs: help carry what crushes your neighbor (v. 2) — but do not let that traffic in burdens become a scoreboard (vv. 3–4) — because in the end the pack each man carries is his own (v. 5). The future βαστάσει is often read eschatologically (the assize of Rom 14:12; 2 Cor 5:10), which grounds v. 4’s future ἕξει in the same frame: the assay now anticipates the audit then.

On either reading of v. 5, v. 4’s logic holds: since the accounting is individual, the standard must be individual too.

The verse is textually stable. NA28 prints it without variation of substance, and it is not treated in Metzger’s commentary — a fair signal that the editorial committee found nothing worth adjudicating.

The minor movements in the tradition are the predictable kinds of smoothing: occasional shifts in the position of μόνον, and some witnesses reading ἑαυτῷ for εἰς ἑαυτόν, which regularizes an unusual referential εἰς into a plain dative. That direction of change is itself evidence for the printed text: scribes normalize an awkward preposition into an expected case, not the reverse.

No variant affects the sense, and none is worth recording in the reading text.

Vulgate: opus autem suum probet unusquisque et sic in semetipso tantum gloriam habebit et non in altero. Three things to note. Jerome renders δοκιμάζω with probet, which correctly carries the assay-and-approve force. He renders καύχημα with gloriam — ‘glory’ rather than ‘ground for boasting’ — which pulls the noun toward the δόξα field and slightly softens it. And he renders both εἰς phrases with in + ablative, adopting the locative construal and setting the direction for the entire subsequent English tradition. This is reception, not evidence (§11), and does not settle the case for the preposition.

Chrysostom reads the verse as directed against the comparative habit specifically: the man who measures himself by a worse man will always find himself adequate, and Paul removes the yardstick. His handling leans toward the ironic construal — the assay is expected to humble, not to gratify — and he ties v. 4 tightly to v. 3’s μηδὲν ὤν.

Jerome, in his commentary on Galatians, presses the connection to v. 5 and reads the future tenses of both verses eschatologically, which is the most natural way to make the paragraph cohere.

The patristic consensus, such as it is, does not treat the verse as licensing self-satisfaction. That reading is a later development and belongs to reception history rather than to the exegetical evidence.
