Yevamot 86: When Kohanim Are Called "Leviim"

Revisiting: Who can eat terumah? Specifically, the women who may have a relationship with a kohen, in various stages (including pregnancy), or various considerations of his status as a kohen. Plus, Ma'aser Rishon, which is the tithing that goes to the leviim. Can the comparable women re terumah eat ma'aser rishon? Note also that those who are excluded from terumah or ma'aser respectively are called "zarim," strangers. Also, a dispute between R. Akiva and R. Elazar Ben Azariah regarding whether ma'aser rishon is given to the kohen instead of to the levi. Tracing through the dispute entails biblical and rabbinic material, as well as practical example from the time of the sages. Plus, the "proof" from the family of R. Tzadok. Plus, additional probing the respective perspectives of R. Akiva and R. Elazar ben Azariah, given that neither convinces the other, despite support from biblical verses and logic and experience.
