זוהר שמות — דף נא ע”ב

The Zohar describes here the heavenly minister of Egypt who gathered six hundred myriads of accusing chariots. On each chariot, six hundred mighty rulers and prosecuting accusers. This is what is written: He took six hundred elite chariots. Egypt s chariot was the last time its supreme level was used, and the Holy One annihilated its power at the splitting of the sea. This scene reveals the war between supernal forces and the divine protection of Israel in its most critical hour.
