זוהר שמות — דף רנט ע”ב

Jacob is above and Joseph below. Jacob’s desire is in the kisses received from the seventh palace, and Joseph’s desire in the service received from the sixth palace. The seventh palace sends selected souls upward, and whoever enters does so in the secret of the holy Name. The seventh palace is called the Holy of Holies of the lower palaces, and its complete Name is YHVH Elohim. The holy Shabbat enters this palace and everything within it is rectified.
