Commentary for Kiddushin 36:9
ואלא מאי אירוסין עושה ושוין שמוכרה הא אין אדם מוכר את בתו לשפחות אחר אישות אלא מאי אית לך למימר שאני אירוסין דידה מאירוסין דאביה אפילו תימא נישואין עושה שאני נישואין דידה מנישואין דאביה
Then It means that her father betrothed her - but a man cannot sell his daughter for servitude after marriage! And thereon R'Amram said in R'Isaac's name: The reference here is to the kiddushin of designation,<span class="x" onmousemove="('comment',' I.e., her father sold her, then her master designated her and died, leaving her a widow.');"><sup>16</sup></span> and [was taught] according to R'Jose son of R'Judah, who maintained: The original money was not given as kiddushin.<span class="x" onmousemove="('comment',' When one buys a bondmaid, the money he pays is not for the purpose of betrothal; and when he designates her, it is by the labour she owes him, not by the money he has given. Therefore her father can resell her after her master's death, and it is not regarded as servitude after betrothal, since he himself did not accept the original money as kiddushin.');"><sup>17</sup></span> But if you say: It effects nissu'in: once she is married, her father no longer has any authority over her! - What then: it effects erusin?
