Remphan

Boyd’s Bible Dictionary:

An idol worshipped secretly by the Israelites in the wilderness
(Acts 7:43). Rephan in R. V. Chiun (Amos 5:26).

Concise Bible Dictionary:

The name of a god in Acts 7:43, which Israel had worshipped (but some of the Greek MSS read REPHAN). Stephen was quoting {vi 22449-22450}Amos 5:25-26 from the LXX, which has RAEPHAN. In the Hebrew the name of the god is CHIUN, but why the translators changed the name is not known. There have been found among the foreign gods in Egypt one named RENPU, and a goddess KEN, which may have been those referred to.
