Sefer HaKaneh is one of the most remarkable works of medieval Jewish mysticism. Modern scholarship dates its composition to the 14th to 15th century. It was composed anonymous, though believed to be composed by a descendant of Rabbi Nechunyah ben HaKaneh, the great mystic and presumed author of Sefer HaBahir. What does the title mean? It has been left untranslated because nearly every possible translation of the word Kaneh (קנה) connects to this book. The work carries a theme of dualities, Du Partzufim, so the title likely reflects more than one meaning. HaKoneh appears once in the Torah, Leviticus 25:28, "the one who acquires," beside the feminine phrase lo matzah, "she could not find," which resurfaces in the last chapter, where the teacher argues that women are not obligated in the mitzvah of eating matzah. The book has 112 chapters: 112 is the gematria of Hashem (26) with Elokim (86), of the river Yabok, and of Mount Eival paired with Gerizim, all dualities. HaKaneh has the gematria of 160: Etz, the Tree of Life; Tzelem, the divine image in Adam. What is special about this work? It is a dialogue between a master and his student, structured around the 613 mitzvot of the Torah. In every chapter the author reveals the mystical dimensions hidden within the mitzvot: the ten sefirot, the divine names, the worlds of emanation, and the interplay between the Written Torah and the Oral Torah. Halachah and Kabbalah are integrated in a way that insists the two are inseparable. Who did this work inspire? The RAMAK, Rabbi Moshe Cordovero, writes in Pardes Rimmonim that Sefer HaKaneh "contains deep secrets of the Torah." His Tomer Devorah opens with "Man is fitting to emulate his Creator (l'kono)," the root of our title; it teaches emulation of Hashem as patterned in the Etz Chaim (Etz = 160), and that Man was created in the Tzelem (160) of Hashem. Both works teach from Micah 7, and the phrase Tomer Devorah comes nearly straight out of Sefer HaKaneh chapter 89, where temarim (date palms) and devorim (bees) stand as the right and left pillars of the sefirot. This is the first full English translation of Sefer HaKaneh: all 112 chapters, over 1,000 notes, and a glossary of Hebrew, Aramaic and Kabbalistic terms. I present to you, the English world: Sefer HaKaneh. —Natan Shmuel (Editor)
