זוהר שמות — דף קעד ע”א

King David in the secret of the Aleph-Bet reveals the mystery of engraved letters issuing from the thirty-two paths. I will give thanks with all my heart: with the evil inclination as well as the good, for everything deserves gratitude. In the secret of the upright and the congregation: between the angels who know the mystery of the Holy One and Israel gathered in a quorum of ten. All souls emerged from the holy body from the place called Yad (Wisdom) whose springs flow to the thirty-two paths. Rabbi Shimon expounding this had tears streaming from his eyes: all the treasuries of the supreme King have been entrusted under one key.
