 Neusner studied Farsi and Middle Persian to do so.Neusner's method of studying documents individually without contextualizing them with other Rabbinic documents of the same era or genre led to a series of studies on the way Judaism creates categories of understanding, and how those categories relate to one another, even as they emerge diversely in discrete rabbinic documents.Neusner, with his contemporaries, translated into English nearly the entire Rabbinic canon.
