Chapter 3, Mishna 12
When do we accept the testimony of a single witness to establish a matter? What was the incident of the deficient mikveh? Who was King Yannai? Why was his advisor Elazar deemed a scoffer with an evil heart and a scoundrel? Who were the Sadducees? Who were the Hasmoneans? Why did Yannai kill so many Sages? Do we invalidate the offerings brought unto the altar in the Holy Temple by a priest who turned out to be blemished? Or who turned out to be the son of a priest who married a divorced woman?
