[If one's wife said:] “Konam, my handiwork to Father” or “to your father” or “to my brother” or “to your brother,” he is unable to revoke it; [“Konam,] my work to you” —- he need not revoke it. R' Akiva says: He should revoke it lest she produce more than his due. R' Yochanan ben Nuri says: He should revoke it lest he divorce her, and she will then be forbidden to him.

[If] his wife vowed, and he thought it was his daughter who had vowed; [or if] his daughter vowed and he thought it was his wife who had vowed; [or if] she vowed [to become] a Nazirite, and he thought that she had vowed concerning an offering; [or if] she vowed concerning an offering, and he thought that she had vowed [to become] a Nazirite; [or if] she made a neder prohibiting figs, and he thought that she had made a neder prohibiting grapes; [or if] she made a neder prohibiting grapes; and he thought that she had made a neder prohibiting figs —- he must revoke the neder again.

[If] she said: “Konam, these figs and grapes, with respect to my tasting [them],” [and] he confirmed [the neder with regard] to figs, it becomes confirmed in its entirety; if he revoked the neder with regard to figs, it is not revoked until he revokes it with regard to grapes as well. [If] she said: “Konam, figs with respect to my tasting [them], and grapes with respect to my tasting [them],” these are two nedarim.

[If a man said:] “I know that there are nedarim, but I did not know that they could be revoked,” he can revoke [the neder]. [But if he said:] “I know that nedarim could be revoked, but I did not know that this was a neder” —- R' Meir says: He cannot revoke [it]; the Sages, however, say: He can revoke [it].
