Berasit (Heb.). The first word of the book of Genesis. The English established version translates this as “In the beginning,” but this rendering is disputed by many scholars. Tertullian approved of “In power”; Grotius “When first”; but the authors of the Targum of Jerusalern, who ought to have known Hebrew if anyone did, translated it “In Wisdom”. Godfrey Higgins, in his Anacalypsis, insists on Berasit being the sign of the ablative case, meaning “in” and ras, rasit, an ancient word for Chokmah, “wisdom”. [ w. w.w.]
Berasit or Berasheth is a mystic word among the Kabbalists of Asia Minor.
