זוהר שמות — דף רז ע”א

The Shabbat paracha stands in the secret of nine sefirot, and nine people are called up: six from weekdays and three when the left side awakens on Shabbat. The paracha is crowned from three sides corresponding to the three supernal sides. Happy is he who merits the honor of Shabbat in both worlds. The verse "Let no man leave his place on the seventh day" means the prohibition against leaving the boundary of holiness, beyond which lies the domain of other gods. "Blessed be the glory of the Lord from His place" - the glory from above is the glory from below, the secret of the crown of Shabbat.
