Pentateuch

Pentateuch (Greek penta, “five”; teuch, “book”), collectively, first five books of the Old Testament, that is, Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. The term was used by the Christian theologian Origen to denote what the Jews of his time called the “Five-Fifths of Torah (teaching).” Pentateuch is the translation of the Hebrew term for this concept. The Torah is the holiest and most beloved of the sacred writings of the Jews. “The Five Books of Moses,” as a designation of the Pentateuch, was first used in the Western church by St. Jerome and the Christian theologian Tyrannius Rufinus. The Mosaic authorship of the work is not directly affirmed in the books themselves, but it became tacitly accepted by Christian orthodoxy. The Pentateuch includes various textual strata of writings, notably the Yahwist (J, which refers to God as Jahwe—modern Jehovah—or Yahweh) and the Elohist (E, which refers to God as Elohim). The Hebrew priest and reformer Ezra, whose work is associated with another textual component of the Pentateuch known as the Priestly stratum (P), gave impetus to observance of the regulations of the Pentateuch.
