Five Hebrew words of preaching. Jonah walks a single day into a city described in v. 3 as three days’ walk, opens his mouth, and the whole oracle is ע֚וֹד אַרְבָּעִ֣ים י֔וֹם וְנִֽינְוֵ֖ה נֶהְפָּֽכֶת — “forty days more, and Nineveh is overturned.” It is the shortest prophetic message in the Hebrew Bible, and the narrator has built the verse so that its brevity is felt: the long measured phrase “a walk of one day” sits against the terse announcement.

Three things carry the weight. First, the verb וַיָּחֶל, “he began” — the narrator tells us Jonah started in and does not say he finished. Second, וַיִּקְרָא, which finally discharges the קרא of the commission (1:2; 3:2) that Jonah had fled. Third, the participle נֶהְפָּכֶת, a niphal of הפך, the verb used of Sodom and Gomorrah (Gen 19:21, 25, 29). A participle of imminence states the overthrow as already in motion, not as a conditional threat — and the root הפך is capable of meaning “turned around” as well as “overthrown,” which is why the verse has been read as an unintended double entendre for at least two millennia.

Notably absent: any mention of YHWH, any call to repent, any condition. Jonah preaches destruction and nothing else. Everything that happens in vv. 5–10 happens without his having offered the Ninevites a way out.

וַיָּ֤חֶל is the hiphil of חלל II, “begin” — a verb that exists in Biblical Hebrew essentially only in the hiphil and hophal in this sense, and must be kept apart from חלל I (“profane”) and חלל III (“pierce”), with which it is homographic. HALOT and BDB both separate the roots; the context (a complementary infinitive לָבוֹא follows) settles it.

The lexical point is narrative, not morphological. “He began to come into the city” reports an inception and leaves the completion unstated. Against v. 3’s “a walk of three days,” the one day’s walk of v. 4 invites the inference that Jonah stopped short — the minimum penetration that could count as having gone. The Hebrew does not assert that he quit; it simply declines to say he went further.

מַהֲלַ֖ךְ י֣וֹם אֶחָ֑ד is an adverbial accusative of extent attached to the infinitive לָבוֹא: he began to come into the city to the extent of one day’s walk. The noun מַהֲלָךְ is picked up verbatim from v. 3 (מַהֲלַ֖ךְ שְׁלֹ֥שֶׁת יָמִֽים), and the repetition is the point — the same measuring word, a smaller measure.

The ordering י֣וֹם אֶחָ֑ד (noun then numeral “one”) is the standard pattern for אֶחָד, which behaves as an attributive adjective rather than as a counting numeral. The athnach falls on אֶחָד, so the Masoretes read the measurement as closing the first half of the verse and the proclamation as beginning the second: the accents divide the verse exactly where the sense does.

Whether the one day is the time taken to reach the centre, or the distance Jonah covered while preaching, the Hebrew leaves open.

וַיִּקְרָא֙ is the verb of the commission. YHWH said וּקְרָא at 1:2 and again וִּקְרָא אֵלֶיהָ at 3:2; here, at last, Jonah קרא. The glossary binds this root to “call out / proclaim” throughout Jonah precisely so that this moment registers in English: the fugitive of ch. 1 is now the herald.

But the verse withholds the object. In 3:2 the content was specified — אֶת־הַקְּרִיאָה אֲשֶׁר אָנֹכִי דֹּבֵר אֵלֶיךָ, “the proclamation that I am speaking to you.” Here Jonah simply calls out, and what follows is introduced by a second verb, וַיֹּאמַר. The narrator does not say that what Jonah said is what YHWH gave him. Readers have drawn the inference both ways for centuries; the Hebrew states only the sequence.

The form וַיֹּאמַ֔ר with pataḥ rather than the expected segol is the pausal vocalization, conditioned by the zaqef qaton. It is a prosodic detail, not a different word.

ע֚וֹד with a time expression means “yet, still, more” — a countdown, not an addition to something already stated: “forty days more” / “yet forty days.” The construction fronts the time span before the clause it governs, which is the regular shape of a deadline announcement.

אַרְבָּעִ֣ים י֔וֹם places the plural decade numeral with a singular noun, the normal Hebrew idiom for measured periods (so also Gen 7:4, 17; Exod 24:18). Forty days is not an arbitrary figure in the Hebrew Bible: the flood (Gen 7:4), Moses on the mountain (Exod 24:18; Deut 9:9), Elijah to Horeb (1 Kgs 19:8). Whether the narrator intends the resonance or simply uses a conventional round span is not decidable from the verse; the rendering should not decorate it.

The number itself is one of the better-known places where the Greek diverges — see the Septuagint section.

The oracle’s one verb. נֶהְפָּֽכֶת is a niphal feminine singular participle of הפך, agreeing with the city-name Nineveh, construed as feminine.

The participle. A predicative niphal participle with no auxiliary states a situation as in force. With a deadline in front of it, the normal force is imminence — the futurum instans of the grammars: “Nineveh is being overturned,” i.e. the overthrow is as good as under way. This is stronger than a plain yiqtol (“will be overturned”) and considerably stronger than a conditional. Jonah announces a done thing with a fuse on it. The literal line keeps the participle (“is being overturned”); the modern line uses the English present-as-imminent (“is overthrown”), which is how English actually says this.

The root. הפך in the niphal is the verb of Sodom (Gen 19:21, 25, 29 use the qal and the related noun; cf. Deut 29:23; Jer 20:16; Lam 4:6, where the Sodom overthrow is named with this root). Its primary force is violent inversion — a city turned upside down. “Destroyed” would be too generic; “overturned / overthrown” keeps the image of inversion.

On the rendering. “Overthrown” is adopted for the modern line and “being overturned” for the literal, so that the root is traceable and the participial force visible. This is proposed as a binding decision for the book.

Three absences are worth naming, because they shape everything from v. 5 to 4:2.

1. No divine name. Jonah does not say who is overturning Nineveh. There is no כֹּה אָמַר יְהוָה, no messenger formula at all. The Ninevites nevertheless believe בֵּאלֹהִים (v. 5) — in God, generically named, which is exactly the vocabulary a Gentile audience would have. The narrator’s alternation of YHWH and אֱלֹהִים is deliberate throughout the book, and it begins here with a proclamation that names neither.
2. No call to repent. The oracle contains no imperative. Everything in vv. 5–9 — fast, sackcloth, crying out, turning from the evil way — is the Ninevites’ own initiative, and their reasoning in v. 9 (מִי־יוֹדֵעַ, “who knows”) is explicitly a guess at divine freedom, not a response to an offered condition.
3. No condition. There is no “unless.” This is what makes v. 10 theologically pointed: YHWH relents from an unconditional announcement. The Hebrew Bible itself articulates the principle in Jer 18:7–8 — a declared judgement on a nation that turns is not executed — and Jonah 3–4 is the narrative case study. Jonah’s complaint in 4:2 shows he understood this from the start, which is why he fled.

The deadline, then, is the whole content of the message: a span of time, and a verb of ruin.

The Greek runs: καὶ ἤρξατο Ιωνας τοῦ εἰσελθεῖν εἰς τὴν πόλιν ὡσεὶ πορείαν ἡμέρας μιᾶς καὶ ἐκήρυξεν καὶ εἶπεν Ἔτι τρεῖς ἡμέραι καὶ Νινευη καταστραφήσεται.

Two differences matter.

τρεῖς for forty. LXX reads three days, not forty. This is the best-known numerical variant in the book. Several explanations are on the table: assimilation to the “three days’ walk” of v. 3 (the likeliest, in most assessments); a genuinely different Hebrew reading; or a deliberate shortening to heighten the urgency. No Hebrew witness known to this writer supports שְׁלֹשֶׁת here, and the Masoretic ארבעים is also what Josephus and the Hebrew-based versions carry. The Hebrew is not corrected toward the Greek; the variant is recorded. The apparatus of BHS and BHQ should be checked for the full witness list before this note is promoted.

καταστραφήσεται. The Greek renders the niphal participle with a future passive indicative, “will be overthrown.” καταστρέφω is the same verb the LXX uses of Sodom (Gen 19:25, 29), so the Greek translator read the root as the threat, not as the pun — and the future tense flattens the participle’s immediacy into a plain prediction. The pun, if it is in the Hebrew, is not transmissible into Greek and the translator did not attempt it.

ὡσεί (“about”) is added before the day’s journey, a small softening with no Hebrew counterpart.

The Vulgate has adhuc quadraginta dies et Nineve subvertetur — forty days, with the Hebrew, and subvertetur, future passive, with the Greek’s tense choice. Jerome translating from the Hebrew is the significant datum for the number.

New Testament. Jesus’ saying about the preaching of Jonah (Matt 12:41; Luke 11:32 — οἱ ἄνδρες Νινευῖται … μετενόησαν εἰς τὸ κήρυγμα Ἰωνᾶ) treats this verse as a κήρυγμα to which the Ninevites responded, and makes their response the indictment of Jesus’ own hearers. The Greek κήρυγμα corresponds to the Hebrew noun קְרִיאָה of 3:2, not to anything in v. 4; the NT reads the whole episode as a unit.

Rabbinic. The Mishnah’s treatment of the fast-day liturgy (Taʿanit 2:1) prescribes that the elder exhort the congregation by pointing to the Ninevites — “it is not said of the people of Nineveh, ‘God saw their sackcloth and their fasting,’ but ‘God saw their deeds’” — a reading grounded in v. 10 rather than v. 4, but it shows that the Ninevite narrative was read as a model of genuine repentance in Jewish liturgical practice. Targum Jonathan renders the verse without substantive expansion, so far as can be stated without checking the critical text.

The forty days as mercy. A reading current in both Jewish and Christian tradition takes the forty-day delay as itself an act of grace: a judgement announced with a deadline is a judgement offering time. This is an inference from the narrative, not from the wording of the oracle, which contains no offer.

Early Church. Jerome’s commentary on Jonah discusses the discrepancy between the Hebrew’s forty and the Greek’s three, and defends the Hebrew. Patristic reading generally pressed the overthrow in a moral direction — Nineveh overturned by conversion rather than by siege — which is the double-entendre reading taken as the spiritual sense. Augustine discusses Jonah’s preaching and the apparent non-fulfilment of the oracle in City of God XVIII, treating the unfulfilled threat as the occasion of Jonah’s anger rather than as a failure of prophecy.

All of this is how the verse was read. Within its own horizon the Hebrew announces a city’s overthrow in five words and stops.
