110 Gittin 6/3-6

(3) [With regard to] a female minor who said, "Accept my bill of divorce on my behalf," it is not an [effective] bill until it has reached her hands. Therefore, if the husband wished to revoke it, he can do so, because a minor cannot appoint a messenger. However, if her father said [to the messenger], "Go and accept my daughter's bill of divorce on her behalf," if the husband wished to revoke it, he cannot. [With regard to] one who says, "Give this bill of divorce to my wife in the place Such-and-such a place" and [the messenger] gave it to her elsewhere, it is invalid. [But had the husband said merely] "My wife is in Such-and-such a place" and [the messenger] gave it her in another place, it is valid. [With regard to] a woman who says, "Accept my bill of divorce on my behalf in Such-and-such a place," and he accepted it for her in another place, it is invalid; Rabbi Eliezer declares it valid. [If she said,] "Bring me my bill of divorce from Such-and-such a place," and he brought it from elsewhere, it is valid.

(4) [If she says,] "Bring me my bill of divorce," she may eat terumah [a portion of a crop given to a Kohen which becomes holy upon separation, and can only be consumed by Kohanim or their household] until the bill of divorce reaches her hands. [If she says,] "Accept my bill of divorce on my behalf," it is prohibited for her to eat terumah immediately. [If she said,] "Accept my bill of divorce on my behalf in Such-and-such a place," she may eat terumah until the bill of divorce reaches that place; Rabbi Eliezer prohibits it immediately.

(5) [With regard to] one who says, "Write a bill of divorce , and give it to my wife," or, "Divorce her," or, "Write her a letter and give it her," they shall write it and give it [to her]. [If he said,] "Release her," or, "Provide her her maintenance," or, "Do with her as is customary," or, "Do with her as is proper," he has said nothing [of significance]. Originally, they would say [that with regard to] one who was being led out with an iron collar [to the place of execution], and he said, "Write a bill of divorce for my wife," they shall write it and give it [to her]. They retracted [that] to say, "Even one who is going to sea, or to travel with a caravan [in the desert]." Rabbi Shimon Shazuri says, "Even one who is dangerously ill."

(6) [With regard to] one who was cast into a pit and said that whoever should hear his voice should write a bill of divorce for his wife, they shall write it and give it [to her]. A healthy person who says, "Write a bill of divorce for my wife," [it is considered as though] he wishes to joke with her. It once happened that a healthy person said, "Write a bill of divorce for my wife," and then went on his roof, and he fell and died. Rabban Shimon ben Gamliel said, "The Sages said, 'If he fell on his own [i.e., purposely], it is a [valid] bill of divorce; if the wind pushed him, it is not a [valid] bill of divorce."
