In this book Jacob Neusner analyzes the text of Sifra, a commentary on the book of Leviticus, arguing that Sifra should be understood as successfully relating the Mishnah, the authoritative writing down of the Oral Torah, to Jewish Scripture, or the written Torah. Neusner shows how Sifra's authors adopted a mediating position between the written Torah and the Mishnah, reconstructing large tracts of the Mishnah according to the logic and program of the written Torah of Leviticus.
