Ketubot 27: Holding Hands: To No Avail
A mishnah: A city that was conquered - the women who were married to kohanim are now forbidden to their husbands. But if there were witnesses that the women were unscathed, they are believed, even if they aren't usually considered credible. Plus, a counter example to weaken the strong mishnah statement, via barrels of wine, even during wartime. What if circumstances indicate that they were protected? The sages know they want to be lenient in these cases - let's call it, "magical halakhic thinking." Also, the very sad story of a kohen who couldn't testify about himself. [Who's Who: R. Zechariyah Ben HaKatzav] || Talmud Principles: A person can't testify on his (or her) own behalf.
