זוהר שמות — דף קעה ע”ב

Happy is the land whose king is a free man: the Supreme King nourishes you in great abundance without fear of another. Woe to the land whose king is a youth: it suckles from the left side and its ministers eat in darkness. The central bar is Jacob the perfect, dwelling in two tents, uniting both sides. Wisdom is the synthesis of all; Hesed emerges from Wisdom and Gevurah from Bina; Jacob completes both sides. The river of Wisdom opened fifty gates of Bina and twenty-two paths were crowned with seventy-two letters of the Holy Name.
