זוהר בראשית — דף ריז ע”א

Who is like You among the mighty, O Lord — these are the supernal angels who question one another. When the Holy One blessed be He split the Sea of Reeds, all the forces above looked on. The angels asked: who is this that cleaves the sea? And the heavens bowed and the earth trembled. Who is like You among the mighty — among all the forces of heaven, how great is the glory of the Name.
