Gittin 2:5 - 2:6

ואפילו חרש שוטה וקטן – [and concerning them – the deaf-mute, imbecile and minor], a Jewish adult stands over them and says to him: Write this for the sake of “so-and-so.” But a heathen and a slave, even if an adult Jew stands over them, ab initio, he should not write the Jewish bill of divorce, because they have the temperament [to write a Jewish bill of divorce], and on their personal knowledge we operate, for even if a Jewish adult says to him: “Write for the sake of “so-and-so” , he should not write other than for himself. But if a heathen or slave wrote the blank form of the document [of the Jewish bill of divorce] and a Jew possessing awareness wrote the part of the document that makes it binding; which is the name of the man and the woman and the time (i.e., date), for all of these require [being written] for their sake (i.e., the man, the woman and the Jewish bill of divorce), the Jewish bill of divorce is valid. And similarly, a when we say in our Mishnah that a deaf-mute, imbecile and/or minor are fit to write a Jewish bill of divorce, these words refer to the blank form of the document, but not the part of the document that makes it binding, is not valid, other than if it is written by an adult Jew who possesses awareness.

חוץ מחרש שוטה וקטן – who all lack awareness.

וסומא – [A blind person] is prohibited from bring a Jewish bill of divorce from outside the land of Israel, because he is unable to say, “it was written in my presence and signed in my presence.” But, to bring a Jewish bill of divorce in the land of Israel, where it is not necessary to say, “it was written in my presence and signed in my presence,” or even in the Diaspora, if the Jewish bill of divorce is verified through its signatories, or to serve as the agent of the woman to receive her Jewish bill of divorce, for all of these, the blind person is considered valid.

ונכרי – he is not [included] in laws of Divorce and Kiddushin/betrothal for the sake of marriage, and anything of his own person is not worthy, he cannot perform the act of agency for another.

קיבל הקטן – [The minor received] the Jewish bill of divorce from the hand of the husband.

והגדיל – [became an adult] prior to his delivery of it [i.e., the Jewish bill of divorce] to her [i.e., the wife].

פתוח ונסתמא וחזר ונתפתח – even if he was not restored to being sighted, since he was able to see at the time when he received the Jewish bill of divorce, he well is able to serve as an agent for he is able to say: “it was written in my presence and it was signed in my presence.” But, since it is required for [the Mishnah] to teach the concluding segment, “and he returned to being sighted,” that he [the agent] must be cognitively aware at the time of the giving [of the Jewish bill of divorce], the Mishnah teaches also at the beginning, “and he returned to being sighted.” But all those who are invalid for testimony through sin, are also invalid to bring the Jewish bill of divorce, for they are not believed to say, “it was written in my presence and signed in my presence.” But if the Jewish bill of divorce is verified through its signatories, they are valid to bring it (i.e., the Jewish bill of divorce).
