Gittin 6:4-5
Gittin 6:4
If a woman (who is married to a kohein) instructs an agent to bring her her get, she may eat terumah until the get is in her hand. If she tells the agent to accept her get for her, she must stop eating terumah immediately (because she doesn’t know when the agent will receive it). If she told the agent to accept her get in a particular place, she may eat terumah for the amount of time it would take to reach that place; Rabbi Eliezer says she must stop eating terumah immediately (because the agent may encounter the husband and receive the get earlier than expected).
Gittin 6:5
If a man told two people, “write a get and give it to my wife,” “divorce my wife” or “write a letter and give it to my wife,” they may write a get and give it to her. If he said, “release my wife,” “support my wife,” “deal with my wife as per the law” or “deal with my wife appropriately,” he hasn’t said anything at all (so if they write and deliver a get, it will be ineffective). Originally the Sages said that if a man is being taken out in chains (to be judged by the government) and said, “write a get for my wife” (omitting the part about delivering it), they could both write and deliver it. They later added that the same applies to one who departs on a sea voyage or a journey with a caravan (which were both dangerous undertakings). Rabbi Shimon Sh’zuri said that the same applies to a person who is dangerously ill.
