Commentary for Avodah Zarah 50:4

This line of the Talmud is very difficult to explain and there are many opinions among rishonim as well as many different readings of the text itself. I will explain according to a dominant opinion which reads the Talmud slightly differently—“ a woman who is considered important among women but not among women.” To R. Yirmiyah, since she is not important among men, meaning she does not have strong ties to the government, she might be murdered. But to R. Idi, all women have their own protection, so we do not need to worry about murder.
Rashi has an entirely different explanation, but since he is universally rejected by later commentaries, I have not explained according to him.
