(Bar Kapara): Even if they left [the husband] when he was 100 years old, and the Shali'ach was 100 years on the road, he gives [the Get] to her based on the Chazakah that he is still alive.

Question: Was it not taught that if [a Kohen] told his wife 'this is your Get; it should take effect a moment before I die', or he told his Shifchah 'this is your Get Shichrur; it should take effect a moment before I die', she is immediately forbidden to eat Terumah? (We are concerned lest he die in a short time!)

Answer: There, from the first moment [she received the Get] she is ruined [forbidden to eat Terumah, lest the Get already took effect, for there is no Chazakah that her husband will continue to live]. Here, only when he dies she is ruined. (The Chazakah is that he is still alive.)

(Mishnah): R. Eliezer ben Parta said three matters (about a man in mortal danger). Chachamim agreed to all of them:

[Someone in] a besieged city, or in a sinking ship, or he is being taken for judgment in a capital case, the Chazakah is that he is alive;

However, if the besiegers conquered the city, or the ship sank, or he was going out to be executed, we apply to him the stringencies of one who is alive and one who died;

[If his wife was] a Bas Kohen married to a Yisrael, or a Bas Yisrael married to a Kohen, she may not eat Terumah.

(Gemara) Question: What is considered a siege?

Answer (R. Ba citing R. Chiya bar Ashi): E.g. there are bells, chains, dogs, geese, chickens (so it will be heard if someone flees) and soldiers surrounding the city.

(R. Ba citing R. Chiya bar Ashi): (A Mishnah teaches that if a city was breached by the enemy, all wives of Kohanim are disqualified, lest they were raped.) A case occurred, and a blind person fled from there [and all the women were permitted. Each could say that also she fled.]

If there was one breach [from which people can flee], it saves (permits) all of them.

Question: If there was a hiding place [where one woman could hide, and they would not suspect that anyone is there, what is the law? Can each say that she his there? Or, since it is impossible that all hid there, all are forbidden?]

(R. Ze'ira citing Rava bar Zavdi citing R. Yitzchak bar Chakulai citing R. Yudan Nesiya): This applies only to a siege of that kingdom, but a siege of another kingdom, they are like bandits. (They fear the kingdom they conquered; they do not defile women.)

They added three others - if a beast was dragging him [to eat him], an overflowing river swept him away, or a house caved in on him, we apply to him the stringencies of one who is alive and one who died;

[If his wife was] a Bas Kohen married to a Yisrael, or a Bas Yisrael married to a Kohen, she may not eat Terumah.
