Remphan, (hrem-fan') is the King James Version of the Bible's rendering of the Greek word variously appearing in Acts 7 verse 43 as Ρομφα, Ρεμφάν, Ρεμφαμ, Ραιφαν, and Ρεφαν. It is part of a quotation from Amos 5 verse 26 where the Septuagint's reading raiphan or rephan stands the Hebrew Chiun or Kewan. The Greek forms are probably simple mistakes for the Hebrew, k (qoppa) having been replaced by r (resh) and ph substituted for v (yod). Kewan is probably the Old Babylonian Kayawanu, the planet Saturn, another (the Akkadian) name for which is Sakkut, which appears as Siccuth in the earlier part of the verse.
By incorrect transliteration for a word of Hebrew origin [H3594]; Remphan (that is, Kijun), an Egyptian idol: - Remphan. In the book of the Acts of the Apostles chapter 7 Stephen points about this deity Remphan the star of your god whose images you made to worship.(verse 43).
