Sefer Hekhalot (3 Enoch)ספר היכלות

Rabbi Ishmael ascends and is received by Metatron — who turns out to be Enoch, the man who "walked with God and was not," transfigured into the Prince of the Presence: flesh become fire, seventy names, a crown like the Ancient of Days', called (scandalously) "the lesser YHVH." Contains the angelic bureaucracy in full: princes of nations, courts of judgment, the curtain (pargod) before the Throne on which all history is embroidered. The scandal-text of the "two powers" controversy — and the reason Metatron got demoted with sixty lashes of fire in the Talmud's telling.
