Chapter 1 Mishna 1 Was it because the majority of the Jews did not return from Babylonia that the Second Temple was destined to be smaller, less holy, and to fall without being rebuilt? Or was it because the Jews were dependent on the Persian Empire when they built it? Both Persia and Rome ultimately fell, but which should be considered “victorious” over the other? We do not place mezuzahs on the gates and doorways of the Holy Temple. Why do synagogues have mezuzahs?
