Guardarás lo que tus labios pronunciaren; y harás, como prometiste á Jehová tu Dios, lo que de tu voluntad hablaste por tu boca.
Guardarás o que teus lábios pronunciarem; e farás, como prometeste ao SENHOR teu Deus, o que de tua vontade falaste por tua boca.
Mais tu observeras et tu accompliras ce qui sortira de tes lèvres, par conséquent les vœux que tu feras volontairement à l’Éternel, ton Dieu, et que ta bouche aura prononcés.
[23:24] Aber was zu deinen Lippen ausgegangen ist, sollst du halten und darnach tun, wie du dem HERRN, deinem Gott, freiwillig gelobt hast, was du mit deinem Munde geredet hast.
Wat uit uw lippen gaat, zult gij houden en doen; gelijk als gij den HEERE, uw God, een vrijwillig offer beloofd hebt, dat gij met uw mond gesproken hebt.
Mantieni e compi la parola uscita dalle tue labbra; fa’ secondo il voto che avrai fatto volontariamente all’Eterno, al tuo Dio, e che la tua bocca avrà pronunziato.
To co wynijdzie z ust twoich, wypełnisz, i uczynisz, jakoś ślubował Panu, Bogu twemu, dobrowolnie, coś wymówił usty twemi.
Что вышло из уст твоих, соблюдай и исполняй так, как обещал ты Господу Богу твоему добровольное приношение, о котором сказал ты устами своими.
你嘴裡 所出的，就是 你口中 應許 甘心所獻的，要照 你向耶和華─你 神 所許的願 謹守 遵行。
Whatever your lips have said, see that you do it; for you gave your word freely to the Lord your God.
Verse in Context
Scholars' Consensus
The commentators agree that this verse establishes the binding obligation of a vow once it is spoken. Gill observes that the command to keep what has gone out of the lips was intended to make the Israelites “watchful and cautious, and not be rash in making vows, since, when once they were made, an exact and rigid performance of them was expected.” Wesley notes that a freewill offering, though voluntary before utterance, “made, yet being made, thou art no longer free, but obliged to perform it.” Keil and Delitzsch explain that nedabah (freewill offering) defines the vow as spontaneous, but that spontaneity does not loosen the duty to fulfill it. The shared point: genuine freedom exists before a vow, but the vow itself creates a sacred bond. Silence or refusal to vow carries no sin; speech does.
How settled is the interpretation?
Interpretive difficulty: Low
What is clear: Once a vow is made to God, it must be fulfilled; the only sin is in vowing and not paying, not in declining to vow.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Binding nature of vows | Christians across traditions agree that once a vow is spoken to God, it must be honored. This is grounded in verses 21, 23 and cross-references like Numbers 30:2. | Some argue that rash or impossible vows (e.g., Jephthah’s) are still binding, while others hold that vows contrary to God’s law should not be kept. The text itself doesn’t address exceptions, leaving room for interpretive disagreement. |
| Voluntariness vs. obligation | All agree that a freewill offering is voluntary before the vow and obligatory after it (Wesley: “thou art no longer free”). | Different traditions emphasize the freedom side more (e.g., the permission not to vow) or the obligation side more (rigorous fulfillment). Protestant commentators often stress the caution against vowing; Catholic moral theology discusses dispensations from vows under church authority. |
| Application to New Testament believers | The principle of truthfulness applies across all promises, not just religious vows (Matthew 5:33, 37). | Some Christians hold that Jesus’ teaching on oaths in the Sermon on the Mount replaces the Old Testament vow system, while others see those words as a call to general honesty rather than an abolition of all vows (e.g., marriage vows). |
Historical & Cultural Context
Deuteronomy 23 belongs to a block of laws governing Israel’s communal life as they prepared to enter the land. The verses immediately before (vv. 21, 22) give the general rule on vows: pay what you vow, and if you refrain from vowing, that is no sin. Verse 23 then specifies that a vow made as a freewill offering must be kept. In ancient Israel, vows were a common way to petition God for help (Hannah, 1 Samuel 1) or to express gratitude (Psalm 66:13, 14). They were not required; the law made clear that God preferred willing offerings over coerced promises. Yet once uttered, a vow carried the weight of a divine covenant, breaking it was both a breach of personal integrity and an affront to God’s holiness.
The term “freewill offering” (Hebrew nedabah) points to a voluntary act of devotion, not something demanded by the law. The surrounding context of Deuteronomy 23 includes laws on interest (vv. 19, 20) and on neighbor’s vineyards (vv. 24, 25), suggesting a broader concern for honesty and generosity in daily dealings. The vow law fits that pattern: honest speech before God mirrors honest treatment of others. The permission not to vow (v. 22) guards against presumption; the command to keep a vow (v. 23) guards against empty religiosity. Together they shape a community that speaks truthfully and worships freely.
Textual Notes
The supplied sources note no significant textual variants for Deuteronomy 23:23. The Masoretic Text is stable across Hebrew manuscripts, and the Greek Septuagint and Latin Vulgate align closely with the Hebrew. The verse’s wording is consistent in all major traditions, so the interpretation rests on the plain text rather than textual uncertainty.
Reception History
Early Christian writers, including Clement of Rome, cited this passage to emphasize the seriousness of promises made to God. In the medieval period, the verse was used to defend monastic vows and pilgrimage pledges. The Reformation brought scrutiny: Calvin and Luther argued that vows should only be made if they are voluntary, lawful, and in keeping with Scripture, using this text to critique coercive vows made under pressure. The Catholic Council of Trent affirmed the validity of religious vows while also reiterating the need for free will. In modern times, the verse is often applied broadly to integrity in all verbal commitments, from marriage vows to tithe pledges, reminding believers that God honors a truthful heart.
Preaching This Verse
Three-point outline
- The freedom not to vow. Verse 22 explicitly permits refraining from vowing. This protects against rash promises and reminds us that God does not demand vows, He desires willing devotion.
- The obligation once vowed. Verse 23 commands that what has left the lips must be done. A vow is not a wish; it is a commitment that binds the speaker.
- The heart behind the vow: voluntary devotion. The freewill offering is a gift from a willing heart, but the free heart is still accountable for its words. True freedom is expressed in faithful keeping of promises.
Five-point outline
- Speech has weight. “That which has gone out of your lips”, words are not neutral; they create obligations.
- Vows are not commanded. God does not require us to make vows; He requires faithfulness to those we make.
- Vows are voluntary. The freewill offering underscores that vows arise from personal devotion, not compulsion.
- Vows are binding. Once spoken, a vow must be performed exactly as promised.
- Integrity is at stake. Keeping a vow reflects God’s own faithfulness and builds trust in the community.
Illustration hooks
- A person makes a midnight promise during a crisis: “God, if you get me through this, I’ll donate my bonus to the church.” The crisis passes. Now what?
- A teenager vows to serve God as a missionary if He saves a relative from illness. Years later, the relative is fine, but the sense of obligation lingers.
- A church member pledges a sum to a building fund, then loses their job. The tension between changed circumstances and a spoken vow is real.
Questions your congregation is asking
- Are vows still relevant today, or did the New Testament end them?
- What if I made a foolish vow or one that I cannot keep?
- How does this apply to things like marriage vows, baptismal promises, or church membership commitments?
Leading a Discussion
This passage draws a clear line between freedom and obligation. Before a vow is made, you are free to speak or stay silent. Once spoken, the word stands. The discussion questions will help your group explore the tension between God’s willingness to receive voluntary offerings and His insistence that those offerings be honored. Encourage honesty about times when promises to God felt burdensome or were broken.
Discussion questions
- What does it mean that the offering is a “freewill offering”? Why does God specifically use that phrase here?
- Compare verse 22 (“if you refrain from making a vow, it shall be no sin”) with verse 23. How does permission to not vow affect the weight of a vow when it does get made?
- Read Judges 11:30, 35 (Jephthah’s vow). Does Jephthah act correctly by keeping his rash vow? What does his story add to the teaching of Deuteronomy 23:23?
- How does this passage challenge our modern culture of casual promises and broken commitments? Where have you seen that tension in your own life or church?
- Psalm 66:13, 14 describes paying vows made in distress. What kinds of distress might lead someone to make a vow today? How can the church help people fulfill such vows without shame?
- In what situations might it be wise not to vow (see Ecclesiastes 5:4, 5)? How can we cultivate the discretion to know when to speak and when to keep silent?
- What does this teaching suggest about the character of God? How does God’s own faithfulness to His promises relate to His call for us to keep ours?

What the Commentators Say
5 public-domain commentaries, condensed into plain language.
Geneva Bible Notes Reformed 1599
The Geneva Bible note stresses that a voluntary vow spoken to God creates a binding obligation. Because the person willingly uttered the promise with their own mouth, they must keep and perform it exactly as spoken. This emphasizes the seriousness of intentional commitments made before God.
Gill's Exposition of the Bible Baptist 1748
Gill stresses that a vow made to God is absolutely binding, requiring exact and rigid performance once promised. He notes that while every vow is a freewill offering, not every freewill offering is a vow, since a vow carries a stricter obligation to fulfill the specific promise made.
Keil & Delitzsch OT Commentary Protestant 1876
Keil-Delitzsch makes a careful distinction: while a vow once made must be fulfilled without delay, never making the vow is not a sin. They also highlight the Hebrew word "nedabah" to show the offering is a matter of free will, given spontaneously, not under compulsion.
Matthew Henry's Commentary Reformed/Presbyterian 1710
For Matthew Henry, the command to shelter an escaped servant turns the land of Israel into a sanctuary for the oppressed. The law protects a fugitive from a harsh master, granting him freedom to settle where he chooses. Israel's borders become a place of refuge for the abused, not a place to return them to bondage.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley highlights a paradox: a free-will offering is freely made, but the act of making it removes the giver's freedom. Once offered, the vow becomes a binding obligation that must be performed, not left undone. Even though no one compelled the promise, the maker is now constrained by it.
