Sikkuth and Kiyyun / Rephan

Astral deities carried in procession. Stephen quotes the Septuagint's Rephan where the Hebrew has Kiyyun, a clean, short case of the Greek Old Testament standing behind a New Testament quotation. Kiyyun is convincingly a form of Kajjamanu, the Babylonian name for Saturn ("the Steady One"), also behind the Syriac Keywan, and the LXX's Greek already shows a scribe confusing Hebrew k for r, which is how Kiyyun became Rephan, or Rompha, by the time Stephen quotes it. Sakkuth is more obscure. DDD's best match is the little-known Babylonian god Sakkud, "cupbearer of the gods," tied to the city of Der on the Elamite border, though the ancient versions (the LXX, and the Damascus Document from Qumran) read the word as "tent" or "tabernacle," "the tent of your king," and not as a divine name at all.
