James closes the wisdom section (3:13-18) not with a further adjective but with a one-line agricultural maxim. Four things carry the weight:

1. καρπὸς δικαιοσύνης — a fixed LXX phrase (Prov 11:30; Amos 6:12) whose genitive is genuinely open. The corpus policy, set at Phil 1:11, is to leave it open.
2. ἐν εἰρήνῃ … εἰρήνην — the noun occurs twice in eight words. The repetition is the argument: peace is both the condition of the sowing and what the sowers do. Neither occurrence may be varied for English elegance.
3. σπείρεται — present passive, agent unexpressed. Whether the unnamed sower is God (divine passive) or the peacemakers themselves depends entirely on how the following dative is taken.
4. τοῖς ποιοῦσιν εἰρήνην — dative of agent (‘by peacemakers’) or dative of advantage (‘for peacemakers’). This is the verse’s chief crux and it is old: the versions already split on it.

The rendering therefore does the minimum: it keeps the sowing image, keeps both occurrences of peace, keeps the genitive bare, and adopts the agent reading in the reading text while flagging the alternative. Everything smoother than that adjudicates something.

καρπός is already fixed corpus-wide as fruit, with the live agricultural metaphor retained (§8) and abstraction to ‘results’, ‘outcome’, or ‘harvest of character’ excluded. The prophetic substrate depends on the image.

καρπὸς δικαιοσύνης is a set phrase in the Greek OT: Prov 11:30 (καρπὸς δικαιοσύνης ξύλον ζωῆς), Amos 6:12 (καρπὸν δικαιοσύνης, of what is turned to poison), and behind them Hos 10:12 (σπείρατε ἑαυτοῖς εἰς δικαιοσύνην). Paul uses it at Phil 1:11 and the phrase is echoed at Heb 12:11 (καρπὸν εἰρηνικὸν … δικαιοσύνης), which is the closest NT parallel to James’s clause and pairs the same two nouns.

The genitive is open three ways:

• Epexegetical — the fruit consisting in righteousness. Favored by Heb 12:11, where righteousness is plainly what is yielded.
• Source — the fruit produced by righteousness.
• Objective/goal — fruit unto righteousness, on the Hos 10:12 pattern.

δικαιοσύνη keeps the single corpus gloss righteousness. Its pole here is ethical-conduct rather than forensic, as at Phil 1:11 — but per §4 the base gloss does not vary and the register is carried in the note. Nothing in James 3 is doing Pauline justification work, and importing that freight would be anachronism running the wrong direction (§9).

Three constructions of the prepositional phrase are live, and they differ materially:

• Sphere — sown within a condition of peace. The peace is the atmosphere in which the sowing happens. This reads most naturally against vv. 14-16, where ζῆλος and ἐριθεία produce ἀκαταστασία: peace is the opposite climate.
• Means — sown by means of peace. Peace is the instrument.
• Attendant circumstance — sown peaceably, i.e. adverbially describing the manner.

The corpus policy on ἐν + dative with abstract nouns (fixed at Phil 1:9) is to retain in, which preserves the ambiguity, and to flag the alternatives rather than tipping with ‘with’ (instrumental) or ‘through’ (decisive). That policy governs here.

The noun is anarthrous and qualitative. εἰρήνη keeps the corpus gloss peace with the Hebraic breadth of שָׁלוֹם — positive wholeness and right ordering, not the Greek negative sense of cessation of hostility — footnoted rather than glossed into the text. That breadth matters here: James is not commending an absence of quarrelling but a settled rightness within which righteousness can grow.

Note the placement. ἐν εἰρήνῃ stands before the verb, between the subject phrase and σπείρεται, which is emphatic; and it is then answered by εἰρήνην at the end of the clause. The verse is framed by peace at both ends.

σπείρω is fixed corpus-wide as sow, with the field-verb retained at every occurrence (Gal 6:7-9; 1 Cor 9:11; 2 Cor 9:6) and abstraction to ‘invest’, ‘produce’, or ‘actions have consequences’ excluded (§8).

Three features of the form:

• Present — durative. This is ongoing agricultural practice, not a single act, and the English present passive carries it. Do not render ‘will be sown’.
• Passive — the agent is unexpressed and must stay unexpressed unless the following dative supplies it. Renderings such as ‘God sows’ or ‘peacemakers sow’ each supply what the Greek withholds.
• Sowing, not reaping — James wrote σπείρεται where the parallel at Heb 12:11 has ἀποδίδωσιν (yields). A crop sown is not yet a crop gathered; the verse concerns what is put in the ground, not what comes out of it.

Proposed — pending reviewMartin Dibelius, James: A Commentary on the Epistle of James, rev. Heinrich Greeven, Hermeneia (Philadelphia: Fortress Press, 1976)

The dative is the verse’s chief crux, and the two readings put the peacemakers on opposite sides of the transaction.

Dative of agent. With a passive verb, a bare dative can name the agent — a construction more at home with perfect passives but attested with presents in Koine (BDF). On this reading the peacemakers do the sowing: they scatter righteousness, and they do it in peace. This is the reading that makes v. 18 the positive counterpart of vv. 14-16, where the quarrelsome sow disorder.

Dative of advantage. The commoner value of the bare dative. On this reading the sowing is done for the peacemakers — most naturally by God, making σπείρεται a divine passive, and the harvest their reward. This reads well against the beatitude form (Matt 5:9, οἱ εἰρηνοποιοί … υἱοὶ θεοῦ κληθήσονται) and against James’s own pattern of promised reward (1:12; 2:5).

ποιέω keeps its corpus gloss do / make. The articular present participle is substantival and characterizing: a class defined by settled practice, not by a single act. Note that James wrote τοῖς ποιοῦσιν εἰρήνην, not the compound εἰρηνοποιός of Matt 5:9 — a periphrasis where a single word existed, which keeps the verb visible and links the class to James’s insistent ποιητής-vocabulary (1:22-25; 4:11). Rendering ‘peacemakers’ is idiomatic English but flattens the participle; the literal tier retains ‘those making peace’.

Proposed — pending reviewRalph P. Martin, James, Word Biblical Commentary 48 (Waco, TX: Word Books, 1988)

δέ is postpositive and, per §10, is always rendered. Two classifications are live:

• Continuative — the maxim adds a summarizing conclusion to the description of wisdom from above (v. 17). This is the reading adopted: v. 17 ends with εἰρηνική heading the list of that wisdom’s qualities, and v. 18 picks the word up.
• Mildly adversative — setting the peaceable sowing against the ἀκαταστασία of v. 16.

The corpus policy is to render δέ per context and never to drop it. And is used here; ‘but’ would manufacture a sharper antithesis than the particle carries at a point where James is drawing a conclusion rather than reversing direction.

On the shape of the sentence: it is a self-contained gnomic maxim, syntactically detachable, in a wisdom register that recalls Prov 11:18, 30 and Isa 32:17 (καὶ ἔσται τὰ ἔργα τῆς δικαιοσύνης εἰρήνη). Several commentators have argued that it is a floating proverb James has attached here. That is a plausible tradition-historical judgment but has no consequence for the rendering: the verse must be rendered as it stands, in the position it occupies (§4).

NA28 prints the verse without a variant unit, and the tradition is essentially stable — the whole verse is transmitted uniformly in the major uncials (א A B C P Ψ) and in the Byzantine text.

What minor movement exists is scribal smoothing of the kind the corpus policy anticipates: a scattering of late witnesses relieve the mixed image or clarify the dative. None has claim to originality, and none is recorded in the NA28 apparatus as significant. The uniformity is worth stating positively: a verse this compressed and this contested exegetically was nonetheless copied without repair, which is evidence that the difficulty was felt to be the author’s.

James is not citing a text but writing inside a field. Four strands feed the line:

• Prov 11:30 LXX — ἐκ καρποῦ δικαιοσύνης φύεται δένδρον ζωῆς. The collocation καρπὸς δικαιοσύνης is already fixed there.
• Prov 11:18 LXX — σπέρμα δὲ δικαίων μισθὸς ἀληθείας. Sowing plus righteousness plus recompense, which is the shape of the advantage reading.
• Hos 10:12 LXX — σπείρατε ἑαυτοῖς εἰς δικαιοσύνην. Sowing toward righteousness, which supplies the mixed image James inherits.
• Isa 32:17 LXX — καὶ ἔσται τὰ ἔργα τῆς δικαιοσύνης εἰρήνη. Righteousness and peace as one complex, which is the whole burden of the verse.

The force of noting these is not that James quotes any of them. It is that the apparent oddities of his sentence — sowing fruit, joining righteousness to peace — are not oddities in the Greek Bible he wrote out of. The English should not iron them out.

The verse is read in the Fathers overwhelmingly as ethical rather than soteriological, which is a useful check on the modern pull to read James’s δικαιοσύνη through Romans.

The Latin tradition renders fructus autem iustitiae in pace seminatur facientibus pacem, preserving the dative’s ambiguity exactly — the Latin dative is as open as the Greek — and so offering no adjudication of the crux. This is worth recording precisely because the Vulgate elsewhere resolves ambiguities James left open (as at 1:25 and 2:1); here it does not, which suggests the ambiguity was felt rather than overlooked.

The Greek commentators characteristically pair the verse with Matt 5:9 and read the sowers as those who cultivate concord in the assembly. That reading is reception, not lexical evidence (§11), and it does not by itself settle the dative — but it does show that the connection with the beatitude was made early and independently.

What is refused, and why:

• ‘a harvest of righteousness’ — adopts the epexegetical genitive and, worse, replaces sowing-language with reaping-language. James wrote σπείρεται.
• ‘peacemakers’ for τοῖς ποιοῦσιν εἰρήνην — idiomatic, but flattens a participial periphrasis James chose over the available compound εἰρηνοποιός, and severs the link to his ποιητής vocabulary. Retained in smooth registers only, with the compression noted.
• ‘by those who sow in peace’ — recasts the passive as an active and dissolves the construction.
• ‘the seed of righteousness’ — repairs the mixed image the LXX itself produced.
• ‘peaceably’ for ἐν εἰρήνῃ — adopts the adverbial reading and, more seriously, breaks the audible pairing with εἰρήνην at the clause’s end.

What is retained: the bare genitive, both occurrences of ‘peace’ in the same English word, the passive with unexpressed agent, the durative present, and the fruit.
