Numbers30:1–16

“He shall not profane his word” — the vow-law restated to the nation structural / thematic — confirmed

Numbers 30:2 lays down the general principle; Deuteronomy 23:21–23 restates it for the whole assembly: when you vow a vow, do not delay to pay it, for the LORD will surely require it — “that which is gone out of thy lips thou shalt keep.” The Verifier records the shared vow-cluster: נָדַר (nādar, in 28 verses), with the same idiom of the word that goes out of the mouth/lips (peh). This is the same law, addressed once to the tribal heads and once to all Israel. Joseph Benson already cited Deut 23:21 here, and Matthew Poole linked the two by the rule of fulfilling “without delay.”

Deuteronomy 23:21 · Deuteronomy 23:23

basis: Verifier: shared lexeme(s) H5087 nâdar (in 28 vv) and the mouth/lips idiom — Numbers 30:2 uses H6310 peh ("from his mouth"), Deut 23:23 H6310 peh ("out of thy lips"). Same vow-law, no quotation claim — restatement, hence structural/thematic.

The vow that should never have been kept — Jephthah and the rash word structural / thematic — confirmed

The chapter assumes rash vows are common (the מִבְטָא, “rash utterance,” of vv. 6, 8) and provides for their lawful release. Judges 11:30–39 is the tragedy of a rash vow with no one to annul it: Jephthah “vowed a vow” and, having none to restrain him, “did with her according to his vow.” The Verifier records the shared vow-cluster נָדַר (nādar, 28 vv) and נֶדֶר (neder, 57 vv). Read together, Numbers 30 is the mercy Jephthah's daughter never received — the household-review and the divine forgiveness that could have spared her. The Pulpit Commentary names exactly this: “Iphigenia in Aulis, Jephthah's daughter in Gilead, proclaim to what horrid extremities any one religious principle, unchecked by other coordinate principles, may lead.”

Judges 11:30 · Judges 11:39

basis: Verifier (Numbers 30:2 ↔ Judges 11:39): shared lexeme(s) H5087 nâdar (in 28 vv), H5088 neder (in 57 vv). Shared motif of the binding/rash vow; no quotation. Moderately rare vow-cluster but a thematic, not verbal, link.

“Better not to vow” — wisdom’s comment on the law structural / thematic — confirmed

Ecclesiastes 5:4–5 reads like the Preacher's meditation on Numbers 30: “When thou vowest a vow unto God, defer not to pay it... Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.” The Verifier records the shared vow-cluster נָדַר (nādar, 28 vv) and נֶדֶר (neder, 57 vv). Cambridge on Numbers 30:2 cites this very text — “The importance of keeping vows is emphasized in Deuteronomy 23:21 ff., Ecclesiastes 5:4 f.” — confirming the link is no novelty. The law's “he shall not profane his word” becomes wisdom's “better not to vow at all.”

Ecclesiastes 5:4 · Ecclesiastes 5:5

basis: Verifier (Numbers 30:2 ↔ Ecclesiastes 5:4): shared lexeme(s) H5087 nâdar (in 28 vv), H5088 neder (in 57 vv). Wisdom restatement of the same vow-ethic; shared vocabulary but no quotation claim — structural/thematic.

The Nazirite — a neder that is positive, not abstinence verbal / quotation — confirmed

Numbers 6:2 opens the Nazirite law with the same formula as 30:2/30:3: אִישׁ ... כִּי יִדֹּר נֶדֶר / a man or woman who “shall vow a vow.” The Verifier records shared נָדַר (28 vv), נֶדֶר (57 vv), and אוֹ (’ôw, “or,” 218 vv). The chapters interpret each other: the Pulpit Commentary uses the Nazirite to correct a common error here — “the Nazarite vow was neder, and that was essentially a vow of abstinence,” warning that neder is not always merely positive. Keil & Delitzsch agree the Nazirite vow “is called neder in Numbers 6:2... not issar.” The two passages together fix the technical vocabulary of vowing.

Numbers 6:2

basis: Verifier (Numbers 30:2 ↔ Numbers 6:2): shared lexeme(s) H5087 nâdar (in 28 vv), H5088 neder (in 57 vv), H176 ʼôw (in 218 vv). The vow-cluster nâdar/neder is the comparatively rare technical formula of vowing, shared as a fixed legal idiom across the two Numbers laws — a verbal/formulaic link within one book, named by K&D and the Pulpit Commentary.

The rare verb of veto — “restrain / hold back” (נוּא) structural / thematic — confirmed

The hinge of the dependent's case is a single rare verb: נוּא (nûʼ, “to restrain, forbid, frustrate, neutralize”), used of the father (vv. 5, 11) and the husband (v. 8) who holds back a vow. The Verifier finds it occurs in only seven verses in all of Scripture — and the only other Pentateuchal occurrences are Numbers 32:7, 9, where the very same verb describes the spies who “discouraged” (held back, turned aside) the heart of Israel from entering the land. The rare lexeme is shared, but the sense is not identical: in chapter 30 the restraining is a lawful, God-sanctioned veto that releases a conscience; in chapter 32 it is a sinful turning of the heart from God's purpose. The same act — holding a will back from a course already set — can be obedience or rebellion depending on whose authority does it and toward what end. The link is recorded as structural rather than verbal because the shared word carries a contrary moral charge in the two contexts; the Verifier's bare lexeme-match is reported but deliberately not over-read.

Numbers 32:7 · Numbers 32:9

basis: Verifier (Numbers 30:5 ↔ Numbers 32:7): shared lexeme H5106 nûwʼ — a genuinely rare verb (only 7 verses canon-wide), the same word for the father/husband's "restrain" and the spies' "discourage." The Verifier auto-tiers a shared lexeme "verbal," but DOWNGRADED here to structural/thematic: the rare root is shared, yet it bears opposite moral valence (lawful release vs. sinful turning-aside) and neither verse quotes the other. Honest under-claim on a strong but sense-divergent lexical tie.

“I vowed a vow” — the great vows of Scripture (Jacob, Hannah) structural / thematic — confirmed

Numbers 30:2–3 sets the law of the vow; the narratives show it lived out. Genesis 28:20 — “And Jacob vowed a vow” at Bethel — and 1 Samuel 1:11 — Hannah “vowed a vow” for a son and gave him back to the LORD — are the two great conditional vows the law presupposes. The Verifier records the shared vow-cluster נָדַר (nādar, 28 vv) and נֶדֶר (neder, 57 vv) in each. The connection is no novelty of the tool's: Cambridge, on Numbers 30:2, cites these very texts to define the vow — “A vow is a promise to give something to God. Such votive offerings were frequent in times of danger or special need (cf. Genesis 28:20-22 , Jdg 11:30 f.).” Numbers 30 supplies the missing safeguard those stories lack a script for: Hannah's vow, made within marriage, would in fact have fallen under her husband Elkanah's review (vv. 10–15) — and the narrative quietly shows him consenting (1 Sam 1:23).

Genesis 28:20 · 1 Samuel 1:11

basis: Verifier (Numbers 30:3 ↔ Genesis 28:20; Numbers 30:2 ↔ 1 Samuel 1:11): shared lexeme(s) H5087 nâdar (28 vv), H5088 neder (57 vv). Shared vow-vocabulary and motif, no quotation in either direction — narrative instances of the law's vow, hence structural/thematic. Grounded in Cambridge's own cross-reference to Gen 28 and Judg 11.

“Let your Yes be Yes” — the word that needs no oath (cross-Testament) flagged — verify source

Numbers 30 governs the binding oath; the Lord Jesus in Matthew 5:33–37 reaches behind it to the heart: “Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths... But I say unto you, Swear not at all... let your communication be, Yea, yea; Nay, nay.” The verse Jesus paraphrases (“perform unto the Lord thine oaths”) is precisely the rule of Numbers 30:2. Because this is Greek text against Hebrew, the Verifier finds no shared original-language lexeme — the connection is thematic and must be argued, not asserted from a Strong's match. Cambridge already pointed the reader from Numbers 30:2 to “Matthew 5:33,” grounding the link in the older commentary rather than in a lexical claim.

Matthew 5:33 · Matthew 5:37

basis: Cross-Testament (Greek↔Hebrew): Verifier returns NO shared Strong's lexeme — by rule a Greek↔Hebrew link cannot be tiered "verbal." The connection is thematic (oath-keeping → Christ's call to truthful speech without oaths) and is asserted on the strength of Matthew's own allusion to OT oath-law plus Cambridge's cross-reference, not on a lexical match. Flagged so the reader verifies the thematic claim independently.

The Substitute who bears the iniquity (v. 15) novel

Numbers 30:15 ends with a startling reversal of the chapter's refrain. Where vv. 5, 8, and 12 close “and YHWH will forgive her,” v. 15 closes “then he shall bear her iniquity” — וְנָשָׂא אֶת־עֲוֺנָהּ. The guilt of the broken vow does not vanish; it is carried by one who stands in the vow-maker's place. The verb נָשָׂא (nāśāʼ, “to lift, bear”) is the very verb of Isaiah's Servant who “hath borne our griefs” and “bare the sin of many” (Isa 53:4, 12), and of the Lamb of God who “taketh away the sin of the world” (John 1:29). Here, in vow-law, the structure of substitution is already cut into the statute: a responsible head bears the iniquity another could not pay. Keil & Delitzsch name the transfer plainly — it is “the sin which the wife would have had to bear if she had broken the vow of her own accord.” The figure is the law's own; that it points to Christ, the perfect Husband bearing His bride's broken vows, is the typological reading — held here as a careful extension, not a claim the text makes in so many words.

Numbers 30:15 · Isaiah 53:12 · John 1:29

“He shall not profane His word” — the One whose vow never breaks widely-held

The whole chapter hangs on v. 2: the man “shall not profane his word.” No human vow-keeper is perfect — which is precisely why the chapter must build in review and forgiveness. But the law's demand of an unprofaned word finds its only flawless fulfillment in Christ, in whom “all the promises of God... are yea, and... Amen” (2 Cor 1:20). Where Israel's words required a household to catch the rash ones and a divine pardon to cover the broken ones, the incarnate Word speaks no rash utterance and breaks no oath: His Yes is Yes (the very ethic of Matt 5:37). The covenant that the chapter assumes God will hold inviolable — He is the LORD to whom every vow is made — is kept perfectly in the Son, whose every word stands (qûm, the chapter's own verb for a vow that holds). Matthew Henry's caution that no vow can bind one to break “the Divine precept” points the same direction: only a will perfectly bound to God's word is a word that can never be profaned. This reading of Christ as the unbreakable Vow-keeper is a widely-held canonical application of the truthful-word ethic, gathered from 2 Cor 1:20 and Matt 5:37.
