זוהר שמות — דף נד ע”א

Moses' soul traverses the Garden of Eden, adorned with three hundred twenty-five crowns, receiving all the King's keys. The letters of Moshe — Mem, Shin, Heh — represent the three holy crowns derived from the Patriarchs. When Moses was born into the world, the letter Heh illuminated his face and the house was filled with radiant glory. The word 'az' (then) is the secret of miracles and mighty deeds, where Aleph and Zayin united illuminate in every direction, destroying the impure forces of Egypt.
