Numbers 30

MOSES SAID TO the heads of the tribes of Israel: “This is what the LORD commands: 2When a man makes a vow to the LORD or takes an oath to obligate himself by a pledge, he must not break his word but must do everything he said.

3“When a young woman still living in her father’s house makes a vow to the LORD or obligates herself by a pledge 4and her father hears about her vow or pledge but says nothing to her, then all her vows and every pledge by which she obligated herself will stand. 5But if her father forbids her when he hears about it, none of her vows or the pledges by which she obligated herself will stand; the LORD will release her because her father has forbidden her.

6“If she marries after she makes a vow or after her lips utter a rash promise by which she obligates herself 7and her husband hears about it but says nothing to her, then her vows or the pledges by which she obligated herself will stand. 8But if her husband forbids her when he hears about it, he nullifies the vow that obligates her or the rash promise by which she obligates herself, and the LORD will release her.

9“Any vow or obligation taken by a widow or divorced woman will be binding on her.

10“If a woman living with her husband makes a vow or obligates herself by a pledge under oath 11and her husband hears about it but says nothing to her and does not forbid her, then all her vows or the pledges by which she obligated herself will stand. 12But if her husband nullifies them when he hears about them, then none of the vows or pledges that came from her lips will stand. Her husband has nullified them, and the LORD will release her. 13Her husband may confirm or nullify any vow she makes or any sworn pledge to deny herself. 14But if her husband says nothing to her about it from day to day, then he confirms all her vows or the pledges binding on her. He confirms them by saying nothing to her when he hears about them. 15If, however, he nullifies them some time after he hears about them, then he is responsible for her guilt.”

16These are the regulations the LORD gave Moses concerning relationships between a man and his wife, and between a father and his young daughter still living in his house.

Original Meaning

A VOW TO GOD is supposed to be an absolute promise. But what happens if you take on such a binding commitment and then discover that another obligation to the Lord, such as honoring your parents (Ex. 20:12), conflicts with your vow?

Numbers 29 has concluded the ritual calendar by saying that the sacrifices for all Israel are aside from offerings that the people vow to give or sacrifice as freewill offerings (29:39; cf. Lev. 23:38); this next chapter picks up on the topic of vows. We have already encountered vows in the contexts of sacrificial votive offerings (Lev. 7:16; 22:18, 21, 23; Num. 15:3, 8), vows to dedicate persons (Lev. 27:2, 8), the Nazirite vow of separation (Num. 6:2, 5, 21), and Israel’s vow to devote the cities of the Canaanite king of Arad to destruction (21:2).

Conveying the divine commands of Numbers 30 through leaders of the patriarchal society (30:1) is appropriate because these commands focus on the family (cf. 27:2; 36:1–4). The role of the “heads of the tribes of Israel” in transmitting a message from God is in welcome contrast to the part perpetrated by the chieftains in the Baal of Peor apostasy (25:1–4).

To provide a baseline for the exceptional situations treated later, chapter 30 begins by affirming a man’s obligation to not violate a vow he has made or a pledge that he has bound on himself by swearing an oath (30:2). A vow is a solemn promise to the Lord, and an oath taken by his name should not be taken in vain and profaned by swearing falsely (Ex. 20:7; Lev. 19:12).

The main concern of Numbers 30 is not with the binding nature of vows and oaths taken by men, but with the tension that can arise when dependent women bind themselves by obligations to God that may conflict with the will of their fathers or husbands, to whom they are legally subordinate in ancient Israelite society (30:16). The vows/obligations of widowed or divorced women, who are independent, are binding like those of men (30:9).

The thrust of this legislation is to benefit dependent women by absolving them of guilt before God when their fathers or husbands do not allow them to fulfill their vows or oaths. Three cases are cited here, following the progression of a woman’s life from single to married status:

• unmarried women subject to their fathers (vv. 3–5)

• women who marry while they are under vows or pledges previously taken (vv. 6–8)

• married women who make vows/pledges while subject to their husbands (vv. 10–15)

The Lord does not allow males to exercise their authority in an arbitrary manner. If a father or husband does not approve of the vow or pledge made by his daughter or wife, he can forbid it only when he first hears of it, in which case God will automatically forgive her for not fulfilling her obligation (30:5, 8, 12). These are the only instances in the Bible of forgiveness (slḥ) automatically guaranteed by statute.1 If the man does not express disapproval the first time the woman’s obligation comes to his attention, his silence constitutes binding consent (30:3–4, 6–7, 10–11, 14). Therefore, if he later breaks her obligation, he is responsible and will bear her culpability (30:15).

Verses 6 and 8 refer to a woman becoming married while still under obligation from a mibṭaʾ, of her lips. This noun appears only here in the Hebrew Bible. It is generally interpreted as a rash/thoughtless utterance (e.g., NASB, NKJV, NIV, NRSV),2 in accordance with the fact that in Psalm 106:33 the Piel verb from the root bṭʾ, describes the rash utterance from Moses’ mouth when he was angry at the waters of Meribah (cf. Num. 20:10). However, because mibṭaʾ, appears only in a case that involves a change of a woman’s status from single to married, it seems clear that her “rashness” is not necessarily a character flaw. Rather, it seems to reflect her inability to foresee the potential effects of a change in circumstances: coming under the jurisdiction of a husband who may feel adversely affected by an obligation she incurred while single.

Singled out for special mention3 is a husband’s right to confirm or annul any obligation that his wife takes to practice self-denial (lit., “afflict oneself”). Presumably it will be of no consequence to him if she chooses to fast for a limited time. However, he will be affected if her self-denial includes other aspects of this kind of mourning observance, especially if she committed herself to abstain from sexual relations. While this possible aspect of self-denial does not explicitly appear in Numbers 30, m. Yoma 8:1 includes abstinence from sexual intercourse in self-denial that is required on the Day of Atonement (cf. Lev. 16:29, 31; 23:27, 29, 32; Num. 29:7).

Bridging Contexts

WORDS ARE NOT CHEAP! Anyone who thinks words are cheap is ignoring the cost of broken trust when promises are broken. Keeping a promise, even (or especially?) if it is to a child, can be a lot cheaper than neglecting or annulling it. The problem with promises is that they are easy to make—especially in the heat of a moment when there is need to express caring, gratitude, or a desire for reconciliation—but can be more difficult to fulfill than first imagined.

A binding obligation to the Lord is set in concrete. Why would anyone make such a promise? Because it is worth more. If you are stuck in a life raft on the Pacific Ocean, with nothing to eat, no water to drink, and sharks circling around, you are likely to make an unconditional commitment that some in this situation have expressed: “Dear God, if you get me out of this alive, I’ll serve you forever!” Somehow it just doesn’t have the same ring to say, “All right, God, if you save my life, I’ll be loving to people when it’s convenient, go to church when I’m not too busy, and give you all the money I have left over after comfortably taking care of myself.”

A promise that is worth more costs more because it binds in an absolute way that is not adaptable to changing circumstances. An Israelite who made such a commitment to the Lord had to honor it if he or she did not want to dangerously damage the divine-human relationship (cf. Eccl. 5:4–5). The only exceptions are stipulated by the Lord himself, who waives his right to receive fulfillment of vows/pledges from dependent women in favor of preserving something highly valuable to him: harmony in the home (Num. 30).

Because of her change of circumstances, the Lord absolves a bride of responsibility to fulfill a prior obligation if her groom has a problem with it (30:6–8). Jephthah and his daughter were not so fortunate: Nobody could annul his vow when he was confronted by a situation that he did not anticipate (Judg. 11). This story illustrates conflict between inviolable promise and extenuating circumstance. Jephthah is an extreme example of someone “who keeps his oath even when it hurts” (Ps. 15:4). Tragically, with utmost sincerity and misguided piety, he kept his oath to honor God at the expense of breaking God’s own law against murder and child sacrifice.4 Surely the Lord would have allowed him to redeem her, as the Israelites later ransomed Jonathan when King Saul uttered a rash curse (1 Sam. 14:24–30, 37–45).

We have found that oaths can cause problems because of human limitations and circumstances (see also Judg. 21:1–7). Jesus presented the proper solution: “But I tell you, Do not swear at all . . .” (Matt. 5:34). He did not say that we should not make solemn commitments to God, but we do not need to unduly bind ourselves.

Contemporary Significance

COMMITMENT AND MUTUAL CONSENT. A modern reader could view Numbers 30 as establishing patriarchal prerogatives at the expense of women’s rights. However, this misses the point of the passage. As with the divine legislation responding to the daughters of Zelophehad (27:1–11), chapter 30 assumes a patriarchal society with the family (rather than the individual) as the basic unit of society and males as the primary legal actors for their families.5 In those days, to be independent as a widow or divorcee was hard, as is illustrated by the story of Ruth. It was more difficult than in our culture, which provides opportunity for many single women to enjoy freedom with financial and legal security.

The legislation of Numbers 30 does not attempt to ignore society, as if timeless divine principles can be lived out in a social vacuum. Nor does it sweep away basic social dynamics in order to institute something better. Rather, it applies divine principles within the context of an already existing patriarchal society. It does not institute a higher level of male control over women, but it protects women from culpability before God that can result from that control. What is astonishing is that the Lord waives his own right in order to safeguard family harmony,6 which is crucial for his people, but which can be fragile.

An Israelite woman’s vow or pledge could be a legal matter that involved her father or husband if she obligated herself to give something that belonged to him, such as an animal for a sacrifice. It would be unfair and generate resentment on his part if he were forced to relinquish something against his will. How would you feel if your child or spouse gave away something that was at least partly yours, which you seriously intended to keep? When it comes to large items, such as vehicles and real estate, there are modern laws to protect co-owners by requiring their signatures of consent to sale or other forms of transfer.

One thing that a woman could vow or swear to give up would be sexual relations during a time of self-denial. Because this would also obligate her husband, it is understandable that Numbers 30:13 requires his consent. Paul later recognized that a prolonged period of sexual abstinence even by mutual consent can open the door for temptation (1 Cor. 7:3–5).

Modern Western society is not patriarchal, at least not to the degree that men have almost exclusive control over the legal structure. Nevertheless, Numbers 30 contains some important principles that transcend the differences between cultures.

1. Promises made to God are serious.

2. We should consider the effects that our vows/pledges may have on other people. Binding obligations, including the marriage vow, should be taken carefully, prayerfully, sparingly, and in counsel with others.

3. Family harmony within the context of a given culture should not be disturbed unless absolutely necessary.

4. By being willing to waive his own rights, the Lord teaches us that we do not always need to insist on our rights.

5. People who control other individuals should not be arbitrary or fickle. Sometimes it is necessary to annul someone’s decision, but there should be a good and consistent reason for doing so.
