Commentary for Kiddushin 38:8
משל לאומר לאשה הרי את מקודשת לי לאחר שלשים יום ובא אחר וקידשה בתוך שלשים יום שמקודשת לשני משל למאן
- I might have thought, But he [her master] did not say 'from now';<span class="x" onmousemove="('comment',' Therefore in the analogous case, even if he says: 'Thou art betrothed unto me after thirty days,' and another man betroths her within the thirty days, she is betrothed to the first.');"><sup>7</sup></span> hence we are informed [that it is not so].<span class="x" onmousemove="('comment',' The above explanation follows Rashi. Tosaf. explains it quite differently: This may be compared etc. Hence here too, if another man betroths her before her master designates her, she is not betrothed to the second, and the subsequent designation of her master takes effect, because the original money was given for kiddushin. 'On whose . . she is not betrothed': which proves that he must actually give her something (sc. her labour, which is worth a perutah) at the end, when he designates her; therefore another man's intervention is valid, and she is betrothed to the second. 'Said R. Aha . . the Rabbis:' just as there, so here too, and the intervention of another man before the master's designation is not valid. The rest is similar to Rashi's explanation.');"><sup>8</sup></span>
Daf Shevui to Kiddushin
The baraita draws a parable to a man who betroths a woman after thirty days. If she accepts kiddushin from someone else within those thirty days, she is betrothed to this second person.
Daf Shevui to Kiddushin
Thus the parable accords with the opinion of R. Yose son of R. Yehudah. He holds that the sale is not akin to betrothal and therefore the father can betroth her to someone else. So too, a man who says “behold you are betrothed to me after thirty days” has not betrothed her until the thirty days are over.
The parable teaches us that even though when buying the girl the master did not state that his kiddushin would not begin until he designates her, this is still like a case of a man who states “behold you are betrothed to me after thirty days.” She is not betrothed until the master actually designates her and if someone else betroths her in the meanwhile, she is betrothed.
