We now turn to Mishnah 7. The Mishnah deals - although it does not say so explicitly - with a case in which the husband attached two conditions to the get, each of which on its own fulfills the condition and validates the get:
That he reach a certain place that he specified - and from the moment he arrives there, the get takes effect.
That he stay away for thirty days and not return - and through this too the condition of the get is fulfilled and it is valid.
Either one of the two, then, is enough: either he reaches the place he specified, or he stays away for thirty days. If he does one of them, the get is valid.
The examples in the Mishnah:
He gave her a get and said: "Harei zeh gitech im lo echzor betoch sheloshim yom" - "This is your get if I do not return within thirty days," and alongside that he made a second condition: that if he travels from Judea to the Galilee, the get takes effect on its own. He was traveling from Judea to the Galilee, reached Antipatris and turned back before going any further - his condition is null and void, and the get is not valid: he did not stay away thirty days, and he did not reach the Galilee either, but only as far as Antipatris.
He said: "Harei zeh gitech im lo echzor betoch sheloshim yom" - "This is your get if I do not return within thirty days," and this time he traveled in the opposite direction, from the Galilee to Judea, and made a second condition: that if he reaches Judea it is a valid get even if he does not stay away thirty days. He reached Kefar Osnai and turned back - his condition is null and void, since Kefar Osnai is not Judea but is considered part of the Galilee. Neither of the two conditions was fulfilled, and therefore the get is not a get.
He said: "Harei zeh gitech im lo echzor betoch sheloshim yom" - "This is your get if I do not return within thirty days," and the second condition was that if he reaches the overseas provinces, that is, outside the Land of Israel, this too would be a valid get. He left the Land of Israel, reached Akko and turned back - his condition is null and void: he did not stay away thirty days, and he did not reach the overseas provinces either, but only as far as Akko.
An interesting point about Akko:
In the first two mishnayos of the tractate we saw that Akko was considered part of the overseas provinces with regard to saying "it was written in my presence and signed in my presence." Tosafos on the first page of the tractate cite Rabbeinu Tam in the name of the Yerushalmi that in fact half of Akko was in the Land of Israel and half was considered part of the overseas provinces. In any case, for our purposes the Mishnah rules that once he went only as far as Akko and turned back, the conditions were not fulfilled and this is not a valid get.
A case in which only one condition was stated:
He said: "Harei zeh gitech kol zeman she'ani rachok sheloshim yom" - "This is your get as long as I stay away for thirty days." Here there is only this one condition. During that period he kept coming back from time to time, and in the end - although the Mishnah does not mention this explicitly - he did stay away for thirty days. Since throughout that whole period, from the giving of the get until his thirty days away, he was never alone with her and never secluded himself with her in private, there is no room to say that perhaps he appeased her and canceled the get. Since he had no opportunity to retract the giving of the get, this is a valid get.
In summary: In this Mishnah we learned about a get to which two conditions were attached, each of which validates the get: arriving at the place the husband specified, or staying away for thirty days. In the three examples - Judea to the Galilee (Antipatris), the Galilee to Judea (Kefar Osnai), and the overseas provinces (Akko) - neither condition was fulfilled, and therefore his condition is void and the get is invalid. By contrast, in the case where only one condition was attached and in the end he did stay away thirty days, the get is valid, since there was no seclusion between them and he had no opportunity to retract.
