Kabbalah

The Bahir — The Book of Brightness

A short, cryptic, and often disordered medieval text was the first work in Jewish history to describe God's emanations using the specific vocabulary of "sefirot" that would define all of later Kabbalah.

Sefer HaBahir, the Book of Brightness, surfaced in twelfth-century Provence, attributed pseudepigraphically to the first- or second-century sage Rabbi Nehunya ben HaKanah, though modern scholarship dates its actual compilation to its medieval appearance, likely drawing on older, possibly Gnostic-influenced esoteric fragments. It is the earliest surviving text to speak explicitly of divine emanations called sefirot as structured, interrelated potencies, including early use of gendered and tree-like imagery for the Godhead that would become standard Kabbalistic vocabulary. The Bahir proceeds through parable, wordplay, and juxtaposition rather than systematic exposition, leading scholars to treat it as a compilation of older esoteric traditions rather than a single author's unified treatise. Its appearance in Provence marks, as far as extant textual evidence shows, the historical starting point of theosophical Kabbalah as a documented literary movement.

Gershom Scholem's landmark studies dated the Bahir's actual compilation to its 12th-century appearance in Provence rather than to its pseudepigraphic first-century attribution.
