Sandalphon
Sandalphon (Hebrew: סָנְדַלְפוֹן; Greek: Σανδαλφών) is an archangel in Jewish and Christian writings. Sandalphon figures prominently in the mystical literary traditions of Rabbinic Judaism and early Christianity, notably in the Midrash, Talmud, and Kabbalah.
Origin
Though not explicitly referenced in scripture, some of the earliest sources on Sandalphon refer to him as the prophet Elijah transfigured and elevated to angelic status. Other sources (mainly from the midrashic period) describe him as the "twin brother" of Metatron, whose human origin as Enoch was similar to the human origin of Sandalphon.
Meaning of name
The name Sandalphon, the protector of unborn children, is possibly derived from the Greek prefix sym-/syn-, meaning "together", and adelphos, meaning "brother"; thus approximately meaning "co-brother", since the modern Greek word for "co-worker", synadelfos (συνάδελφος), has these roots as seen in the Book of Revelation, chapter 19, verse 10. This probably refers to Sandalphon's relationship to Metatron, though this derivation shows uncertain Semitic influences. Another possibility is it coming from the Greek sandalion, meaning "sandal"; thus meaning "one who wears sandals".
