A woman who was imprisoned by gentiles: if because of money —- is permitted to her husband; [but if it was] for the purpose of [taking her] life, she is prohibited to her husband.  A city that was conquered by a besieging troop —- all Kohanim’s wives found therein are unfit. But if they have witnesses —- even a slave, even a maidservant —- these are believed. A person is not believed about himself. Said R’ Zechariah ben HaKatzav: [By] this Temple! Her hand did not move out of my hand from the time the gentiles entered Jerusalem until they left. They said to him: A person cannot testify for himself.
