Sifra (“The Book”) is a halakhic (legal) midrash on the book of Leviticus, frequently quoted in the Talmud. Compiled in the early talmudic period, the identity of its compiler has been subject to debate since medieval times. Most of the work is written in the style of the school of Rabbi Akiva, while two sections — one about forbidden relations and the other on the dedication of the Mishkan — are written in the style of the school of Rabbi Yishmael.
