Remphan

(Acts 7:43) and Chi'un, (Amos 5:26) have been supposed to be names of an idol worshipped secretly by the Israelites in the wilderness, difficulty has been occasioned by this corresponding occurrence of two names so wholly different in sound. The most reasonable opinion seems to be that Chiun was a Hebrew or Semitic name, and Remphan an Egyptian equivalent substituted by the LXX, and you can find more about that here on st-takla.org on other commentaries and dictionary entries. This idol corresponded probably to Saturn or Molech. The mention of Chiun or Remphan as worshipped in the desert shows that this idolatry was, in part at least that of foreigners, and no doubt of those settled in lower Egypt.
