When a person takes a vow or an oath and at the time of the vow or the oath specifies a stipulation for which he is making the vow, it is as if he made the vow or the oath dependent on that matter. If the stipulation for which he took the oath is not fulfilled, he is permitted [to act as if the oath had never been taken].
What is implied? If he took an oath or vow saying: "I will not marry this-and-this woman whose father is evil" or "I will not enter this house, because there is a harmful dog within it," if they died or the father repented, he may [do so]. This is comparable to someone who says "I will not marry so-and-so..." or "...not enter this house unless the harmful factor is removed." Similar laws apply in all analogous situations.
[A different rationale applies] when one takes a vow or an oath: "I will not marry so-and-so who is ugly," and it is discovered that she is beautiful, (Yoreh De'ah 232:6)]. "...who is dark-skinned," and it is discovered that she is light-skinned, "...who is short," and it is discovered that she is tall, or "I am taking a vow that my wife shall not benefit from me, because she took my wallet and beat my son," and it was discovered that she did not take it or beat him. He is permitted, because the vow was taken in error. It is included among the category of inadvertent vows that are permitted. This does not resemble an instance where the vow was made dependent on a stipulation and that stipulation was not kept. For the reason for which the vow was taken never applied. Instead, it was an error [of perception].
Moreover, even if a person saw from a distance that people were partaking of his figs and he said [concerning] them: "They are like a sacrifice for you," but when he came close to them and looked [at them], he saw that they were his father and his brothers, they are permitted [to partake of them]. Even though he did not explicitly state the reason why he took a vow [forbidding] them, it is as if he did. For it is obvious that he forbade his produce to them only because he thought they were people at large. Similar laws apply in all analogous situations.
🔍 Premise Fails
A vow built on a stated condition that turns out to be false is annulled — not released by a sage but structurally void from the start. If the condition was unstated but clearly the sole motivating factor, the same logic applies. The Rambam draws a sharp line between an explicit stipulation (immediately void) and an implicit motive (requires inquiry).
When a person took a vow or an oath and then a factor came up that was not in his mind at the time he took the oath or the vow, he is forbidden [in the matter] until he requests a sage to release his vow. What is implied? A person forbade himself from benefiting from so-and-so or from entering this-and-this place and that person became the city scribe or a synagogue was made at that place. Even though he said "If I knew that this person would become the scribe or that in this place a synagogue would be made, I would not have taken the vow or the oath," he is forbidden to benefit [from the person] or enter the place until he has his vow released, as we explained. 6:5, 12. As stated there, the vow was not made initially in error, for at the outset, he did not desire that the person become the scribe. Hence, the oath takes effect. The Ra'avad suggests that the statement from Halachah 3: "This does not resemble an instance where the vow was made dependent on a stipulation and that stipulation was not kept" should be included here, for this is a different category of vows than those mentioned in the previous halachot. Similar laws apply in all analogous situations.
Whenever a portion of a vow is nullified, the entire vow is nullified. 1:1 derives this from the exegesis of Numbers 30:3: "He shall do all that he utters from his mouth." Implied is that everything that he utters must be fulfilled or the vow does not take effect. Rabbenu Nissim gives a logical explanation for this concept. At the outset, his intent was that the vow would be kept in its entirety. If a factor arose that prevented that from taking place, it is as if the vow was taken in error. This law also applies with regard to oaths. What is implied? A person saw from a distance that people were partaking of his figs and he said [concerning] them: "They are like a sacrifice for you," but when he came close to them and looked [at them], he saw that they were his father and people at large. Since his father is permitted [to partake of them], they are all permitted. Even if he said: "So-and-so and so-and-so are forbidden and my father is permitted, they are all permitted. If, however, when he reached them he said: "If I would have known that my father is with you, I would have said: 'You are all forbidden [to partake of my produce], except my father,' they are all forbidden except his father. For he revealed his intent was not to release a portion of his vow,). In his Shulchan Aruch (Yoreh De'ah 232:8), Rav Yosef Caro appears to follow a slightly different rationale. but to make a vow as he did, but to make a stipulation concerning his father.
⚡ Domino Rule
When a factor unforeseen at the time of the vow arises, a sage may release the vow on that basis. Even more striking: if any portion of a vow is nullified — whether by sage or by the nullification of a condition — the entire vow falls. Partial vows have no independent existence.
Similar [laws apply] when one says: "Wine is like a sacrifice for me, because wine is bad for digestion," but he was told: "Aged wine is good for digestion." If he said: "Had I known, I would not have taken the vow" or even: "Had I known, I would have said: 'Fresh wine is forbidden, but aged wine is permitted,' he is permitted [to drink] both fresh wine and aged wine. If, however, he said: "Had I known, I would have said: 'All wine is forbidden for me except aged wine,' he is permitted [to drink] only aged wine. Similar laws apply in all analogous situations.
Whenever a person takes a vow or an oath, we consider the motivating factor for the oath or the vow and extrapolate from it what the person's intent was. We follow his intent, not the literal meaning of his words. 218:1) emphasizes that this applies when a person takes a vow on his own initiative. If, however, he takes a vow in response to wording chosen by a colleague, we follow the meaning of that wording. What is implied? He was carrying a load of wool or of linen and was perspiring, causing a foul odor. If he took an oath or a vow that he would never have wool or linen upon him again, he is permitted to wear woolen or linen clothes and cover himself with them. He is only forbidden to carry them on his back like a burden. If he was wearing woolen clothing and became aggravated because of these garments and took an oath or a vow that he would never have wool upon him again, he is forbidden to wear [woolen clothes], but is permitted to carry wool and to cover himself with woolen spreads. For he intended only [to forbid] woolen clothes. Similar laws apply in all analogous situations.
[Similar laws apply if] people were asking him to marry his relative, 62b). but he refused and they pressured him, so he took a vow or an oath that she could not benefit from him forever. Alternatively, a person divorced his wife and took an oath that she would never benefit from him. These women are permitted to derive [ordinary] benefit from him. His intent was that only [to prevent himself from] marrying them.
Similarly, if a person called to his friend, [inviting him] to eat at his [home] and he took an oath or a vow not to enter his home or even drink cold water of his, he is permitted to enter his home and drink his water. His intent was only that he would not eat and drink with him at that feast. Similar laws apply in all analogous situations.
🎯 Root Intent
We do not read a vow in a vacuum — we extrapolate from the motivating factor. A vow driven by social pressure ("people were pressuring me to marry her") is interpreted against that backdrop. If the context dissolves — the pressure lifts, the friend relents — the vow's scope may narrow or collapse. Context is legally constitutive, not merely explanatory.
When a person takes a vow or an oath, telling a colleague: "I will never enter your house" or "...buy your field," and [that colleague] dies or sells [the property] to someone else, [the person who took the vow] is permitted to enter the house or purchase the field from the heir or from the purchaser. 216:10). His intent [when establishing the prohibition] was only for the time they belonged to [the original owner]. If, by contrast, he said: "I will never enter this house" or "I will never purchase this field," even if [the original owner] dies or sells [the property] to someone else, [the person who took the vow] is forbidden.
[The following laws apply when a person] asks a colleague: "Lend me your cow," he answers him: "She is not free," and [the first person] takes an oath or a vow,). saying: "I will never plow my field with it." If he is accustomed to plowing his field himself, he is forbidden to plow [his field with that cow], but any other person is permitted to plow [his field] with it. If he is not accustomed to plowing his field himself, both he and everyone else is forbidden to plow [his field] with it. Similar laws apply in all analogous situations.
When a person takes an oath or a vow that he will marry a woman, purchase a house, 80a mentions purchasing a house or marrying a woman in Eretz Yisrael, the commentaries [nor the Shulchan Aruch (Yoreh De'ah 219:1)] see no reason why the Holy Land is different from other places in this regard. depart with a caravan, or set out to sea, we do not obligate him to marry, make the purchase, or set out immediately. Instead, he may wait until he finds something appropriate for himself. An incident occurred concerning a woman who took a vow that she would marry anyone who asked her to marry him. Men who were not appropriate for her jumped at the opportunity. Our Sages ruled that her intent was [to marry] anyone from among those appropriate for her who asked her. Similar laws apply in all analogous situations.
When a person administers a vow to a colleague or takes an oath telling him to come and take a kor of wheat or two barrels of wine for his son, [the colleague] can release the vow without asking a sage to do so. [He need only] say: "Your intent was only to honor me. (Yoreh De'ah 332:20) states that the person who administered the vow need not explicitly agree to this interpretation. Even if he remains silent, we accept it. The Siftei Cohen 332:46 states that if the person specifically says that he administered the vow so that he would receive honor by having the other person receive a gift from him, his word is accepted and a sage must be approached to have the vow released. It is a greater token of respect for me not to take [the gift]. I already received the honor that you desired to give me through your vow." Similarly, if one took an oath or a vow: "You may not derive any benefit from me until you give my son a kor of wheat and two barrels of wine, he can release the vow without asking a sage to do so. [He need only] say: "It is as if I received them and they reached my hand." Similar laws apply in all analogous situations.
🤝 Changed Circumstances
Vows tied to specific transactions or relationships — "I will never enter your house," "I will never buy your field" — are bounded by the state of affairs at the time of the vow. If the house is sold, the field transferred, the original locus of the vow may no longer apply. Administered vows (one person vowing another to perform) follow their own logic of reasonable expectation.

Vows Have Architecture Every vow rests on premises — stated or implied. Identify them, and you identify the vow's boundaries and potential vulnerabilities.

The Whole Collapses With the Part Partial nullification is total nullification. There is no such thing as a 'half-vow' — once the foundation cracks, the entire structure falls.

Intent Over Literalism Halacha reads vows through the lens of their purpose. The words matter, but the motivating context determines what those words actually obligate.

Circumstances Are Part of the Vow A vow is not an isolated declaration — it is embedded in a web of facts. When those facts shift dramatically, the vow shifts with them.
