Sifra and Sifre

Legal midrash on Leviticus, Numbers, and Deuteronomy.


When we hear the word “midrash,” we usually think about the rabbinic stories that embellish biblical texts. We might remember the tale about Abraham destroying his father’s idols or the story about God prohibiting the angels from rejoicing over the drowning Egyptians. But aside from these narrative midrashim there is a second form of midrash, which concerns itself primarily with legal exegesis. For the sake of simplicity, these two genres are designated as midrash aggadah (narrative midrash) and midrash halakhah (legal midrash). Reality, however, is more complicated–midrash aggadah often includes legal teachings, while midrash halakhah also contains narrative material.

Three Collections

Three of the major collections of midrash halakhah are Sifra–a commentary on the book of Leviticus, and two collections both known as Sifre–one on the book of Numbers and the other on the book of Deuteronomy. The word “sifra” simply means “book” in Aramaic. Traditionally, Jewish schoolchildren began their Torah studies with the book of Leviticus; one text explains this practice by noting that “pure” children are well-suited to study the laws of purity (Vayikra Rabbah 7:3). Whatever the reason for this pedagogical choice, the primacy of Leviticus resulted in its designation as “the book.” The major midrashic work on Leviticus also became known as Sifra or “book.” The halakhic midrashim on Numbers and Deuteronomy, though two separate works, were often transmitted together. These books therefore became known as “Sifre,” or “books.”

The legal midrashim on the book of Exodus were probably originally included in the Sifre, but by the Middle Ages, they acquired their own identity as Mekhilta. Because the book of Genesis teaches virtually no laws, there is no collection of midrash halakhah  on Genesis. Sifre Zuta (literally: little books) is a collection of midrashim on the book of Numbers. The text of Sifre Zuta was not preserved, and is known to us only through fragments quoted elsewhere. In modern times, scholars have reconstituted and published these fragments as a unified work.
