ד ותיפוק ליה דמתנה על מה שכתוב בתורה הוא וכל המתנה על מה שכתוב בתורה תנאו בטל
4 — R. Adda the son of R. Ika replied: When we say that where a stipulation is made to break an injunction laid down in the Torah the condition is void, we refer for instance to a stipulation to withhold the food, raiment and marriage duty [of a married woman], where it is the man who nullifies the injunction, but here it is she who nullifies it, Rabina strongly demurred to this [saying], Is not her whole purpose in nullifying only to carry out his condition, so that in point of fact it is he who nullifies? No, said Rabina. When we say that wherever a stipulation is made to break an injunction laid down in the Torah the condition is void, we mean, for instance, [a stipulation] to withhold her food, raiment and marriage duty, where he is unquestionably nullifying [the injunction]. But in this case [will anyone tell her that] she is absolutely bound to eat? She need not eat and will not be divorced.
