Paul is closing the letter with a delicately worded acknowledgment of money. In v. 15 he said that at the beginning of the gospel, when he left Macedonia, no assembly entered into a ledger of giving and receiving with him except the Philippians alone. Verse 16 supplies the proof: even in Thessalonica — that is, before he had gotten clear of Macedonia at all — they had already sent for his need, and not once only.

Three things carry the weight, and all three are terse to the point of ellipsis:

1. καί before the place-name is adverbial (‘even’), not connective (‘and’). It marks Thessalonica as a surprising early instance, not an additional stop on a list.
2. καὶ ἅπαξ καὶ δίς is a fixed Greek idiom for repeated action; whether it counts to exactly two is the main interpretive question of the verse.
3. ἐπέμψατε has no object. Paul says ‘you sent’ and lets the reader supply what was sent — a reticence that runs through the whole paragraph (contrast the frankness of τὸ δόμα, v. 17).

The verse is therefore an accounting entry with the amount left blank on purpose.

ὅτι here is not the complementizer of v. 15 repeated (‘you know that … that …’) but almost certainly causal: it grounds the claim of v. 15 by producing evidence. Rendering ‘that’ would suggest a second object of Οἴδατε, which is grammatically possible but produces a clumsy double complement after an intervening full clause.

The glossary already fixes ὅτι after verbs of confessing as recitative-or-complementary; here the standing policy for epistolary connectives applies (§10): render it, do not drop it. ‘Because’ makes the evidential relation visible in English.

The καί stands immediately before a prepositional phrase and is therefore adverbial — the glossary entry fixed at Phil 1:18 applies without alteration: render even, never silently delete. Paul is not adding Thessalonica to a list of donor-locations; he is naming it as the astonishing earliest case.

Why astonishing? Because v. 15 said the partnership began when I left Macedonia, and Thessalonica is in Macedonia. Two readings of the locative follow.

ἅπαξ (‘once’) and δίς (‘twice’) joined by correlative καί … καί form a recognized idiom. The question is arithmetical honesty: does Paul mean exactly two gifts, or is this the Greek equivalent of ‘time and again’?

The evidence for the idiomatic sense is good. The same phrase appears at 1 Thess 2:18 (καὶ ἅπαξ καὶ δίς, of Paul’s repeated attempts to visit), and the LXX has the cognate pattern ἅπαξ καὶ δίς at 1 Kgdms 3:10 and 3 Kgdms 22:16 for repeated action without a strict count. Nehemiah 13:20 LXX (ἅπαξ καὶ δίς) likewise means ‘repeatedly.’

Against pure idiom: the immediate context is a ledger (λόγον δόσεως καὶ λήμψεως, v. 15), and in an accounting frame a count may be meant literally. Lightfoot’s reading — ‘more than once,’ i.e. indefinite but small — sits between the poles and is probably the honest place to land.

The rendering adopted here — ‘both once and twice’ in the literal tier, ‘and did so more than once’ in the smooth tier — keeps the numerals visible where a reader can check them and gives the idiom its force where English needs to read naturally.

χρεία is concrete lack — what a person actually goes short of. The glossary already fixes ‘need’ over ‘necessity’ (Phil 2:25), and the same noun reappears at 4:19, where God is said to fill πᾶσαν χρείαν ὑμῶν. The echo is deliberate: they met Paul’s χρεία, and God will meet all of theirs.

εἰς is directional-telic: the gift was aimed at the need. Not ‘because of my need’ (that would be διά + acc.) and not ‘in my need’ (which would make it a circumstance rather than a target).

The dative μοι is best taken as advantage (‘sent to me, for the need’) or, less formally, as possessive with χρείαν (‘my need’). Article + noun with a dative pronoun functioning possessively is ordinary Koine; the smooth rendering resolves it that way, and the literal tier keeps the two elements separate so the reader can see there is no ὑμῶν-style genitive in the Greek.

πέμπω, per the standing glossary decision, is the plain verb of dispatch — not ἀποστέλλω with its commissioning nuance. The aorist is complexive: the whole sequence of sendings viewed as one completed fact.

The striking feature is the missing object. Greek permits it; English strains. Any supplied object is an interpretive addition and is therefore bracketed in the modern tier. Paul’s habit through this paragraph is to name the money by circumlocution and then to reframe it — τὰ παρʼ ὑμῶν (v. 18), ὀσμὴν εὐωδίας, θυσίαν δεκτήν. The reticence is not embarrassment but theology: what arrived was a sacrifice offered to God, and Paul refuses to reduce it to a transaction even while keeping the books.

The wording is stable in the critical editions; NA28 prints the verse without variation units of substance. Two minor matters in the wider apparatus deserve a note:

• Some later witnesses read εἰς τὰς χρείας (plural), harmonizing to the repeated sendings. The singular is better attested and is the harder reading — a scribe pluralizing after ἅπαξ καὶ δίς is far more likely than the reverse.
• The particle sequence καὶ … καὶ … καί is smoothed in a few minuscules by dropping the first καί, which is exactly the deletion a modern translator is tempted to make. That the Byzantine tradition largely resists it is worth noting: the adverbial καί was felt as meaningful.

Metzger’s committee records no discussion for this verse, which is itself data: the transmission of Phil 4:15–16 is quiet.

Chrysostom (Hom. in Phil. 15) takes the point of the verse to be the Philippians’ promptness rather than the size of the gift: they gave at the outset, when Paul was newly gone and least established, and they alone. He reads καὶ ἐν Θεσσαλονίκῃ as intensifying — Paul is praising them for not waiting.

Theodore of Mopsuestia and Theodoret similarly treat the ἅπαξ καὶ δίς as evidence of repeated, habitual care rather than a tally. None of the Greek Fathers presses the numerals; this is early support for the idiomatic reading, and it comes from readers for whom the phrase was living Greek.

The Latin tradition renders et semel et bis, keeping both numerals — a formal-equivalence choice that leaves the ambiguity open, as the rendering here does.

Verses 15–18 are sustained commercial vocabulary: λόγον δόσεως καὶ λήμψεως (a debit-and-credit account), ἀπέχω (v. 18, the receipt formula ‘paid in full’ known from the papyri), καρπὸν … εἰς λόγον ὑμῶν (v. 17, fruit credited to their account). Verse 16 supplies the dated entries.

Per §8, this is a live metaphor, not a dead one — Paul is deliberately talking about the Philippians’ generosity in the language of a business partnership, and then in v. 18 he converts the whole account into cultic terms (ὀσμὴν εὐωδίας, θυσίαν δεκτήν). The English should keep the bookkeeping audible in v. 16 (‘sent … for my need,’ ‘once and twice’) rather than warming it into generalized gratitude. The warmth arrives in v. 18, and it arrives as sacrifice, not as sentiment.
