(2) And furthermore Rabbi Eliezer said: They make an opening for a vow by reference to a new fact; but the Sages forbid it. How so? He said, “Konam that I will not benefit from so and so,” and he [the latter] then became a scribe, or was about to give his son in marriage, and he said, “Had I known that he would become a scribe or was about to give his son in marriage, I would not have vowed;” [Or if he said,] “Konam, is this house that I will not enter,” and it became a synagogue, and he declared, “Had I known that it would become a synagogue, I would not have vowed,”—Rabbi Eliezer permits [the vow to be released], but the Sages forbid it.
(3) Rabbi Meir says, there are things that are like a new fact but are not like a new fact, but the Sages didn't agree with him. How is this? He said "Konam that I will not marry so and so because her father is wicked." They said to him, "He [the father] died" or "he has repented [from his wicked ways]." [He said:] "Konam, is this house that I will not enter because the dog inside it is bad," or "there is a snake inside it." They said to him, "The dog has died" or "the snake was killed." These cases are like a new fact but not a new fact. But the Sages did not agree with him.
(4) Further, Rabbi Meir said, we make an opening from verses in the Torah and say to him, "If you had known that you would transgress (Leviticus 19:18) "don't take revenge" or "don't bear a grudge" and (Leviticus 19:17) "don't hate your brother in your heart" and (Leviticus 19:18) "love your neighbor as yourself" and (Leviticus 25:36) "that your brother may live with you" [because] maybe he will become poor and you will not be able to support him?" And he responds "Had I known that it is so, I would not have vowed," his vow is released.
(5) They make an opening for a person by reference to a wife’s ketubah. And it once happened that a man vowed not to benefit from his wife and her ketubah amounted to four hundred denarii. He went before Rabbi Akiva, who ordered him to pay her the ketubah. He said to him, “Rabbi! My father left eight hundred denarii, of which my brother took four hundred and I took four hundred. Isn’t it enough that she should receive two hundred and I two hundred?” Rabbi Akiva replied: even if you have to sell the hair of your head you must pay her her ketubah. He said to him, “Had I known that it is so, I would not have vowed.” And Rabbi Akiva released his vow.
