פירוש על קידושין 120:11

R. Yehudah, as we learned earlier, holds that there is also a tannaitic dispute over the meaning of “on condition [that I die].” Only Rabbi holds that this is equivalent to “from now.” The other sages would say that this is also ambivalent and thus she is only doubtfully divorced. So then, the Talmud asks, why don’t we have a baraita in which the tannaim disagree over this subject, and from that dispute we could learn that all the more so they disagree over “from today and after death.”
