The star was mentioned and condemned by the God of Israel in Amos 5:26 and it was called by Him, `the star of your god, Moloch’ or otherwise called `Chiun’. Reference to Amos 5:26 and the Israelites having it in the wilderness was also made in Acts 7:43. Here it was called the Star of Remphan. All these names refer to the `god’ Saturn. The hexagram was brought to the Jewish people by Solomon when he turned to witchcraft and idolatry after his marriage to Pharaoh’s daughter in 922B.C. It became known as the Seal of Solomon in Egyptian magic and witchcraft. David had absolutely nothing to do with the hexagram and that star most certainly did not, in any way, represent God’s people. Solomon gave himself up to satanic worship and built altars to Ashtoreth and Moloch (Saturn).
There is also a school of thought this way, The martyrdom of Stephen episode in the Book of Acts seems to indicate the star of Rephaim is the symbol of babylonic/cabalistic jewry-the six sided star of Solomon.
Gill’s Exposition of the Entire Bible explains it this way;
The Alexandrian copy reads “Raiphan”; some copies read “Raphan”; and so the Arabic version; others “Rephan”; the Syriac version reads “Rephon”; and the Ethiopic version “Rephom”. Giants, with the Hebrews, were called “Rephaim”; and so Mo, who is here meant, is called “Rephan”, and with an epenthesis “Remphan”, because of his gigantic form; which some have concluded from the massy crown on his head, which, with the precious stones, weighed a talent of gold, which David took from thence, 2 Samuel 12:30 for not the then reigning king of the Ammonites, but Molech, or Milchom, their idol, is meant: this is generally thought to be the same with Chiun in Amos; but it does not stand in a place to answer to that; besides, that should not be left untranslated, it not being a proper name of an idol, but signifies a type or form; and the whole may be rendered thus, “but ye have borne the tabernacle of your king, and the type, or form of your images, the star of your god”; which version agrees with Stephens’s, who, from the Septuagint, adds the name of this their king, and their god Rephan, or Remphan. Drusius conjectures, that this is a fault of the Scribes writing Rephan for Cephan, or that the Septuagint interpreters mistook the letter for and instead of Cevan read Revan; and Chiun is indeed, by Kimchi and Aben Ezra (h), said to be the same with Chevan, which, in the Ishmaelitish and Persian languages, signifies Saturn; and so does Rephan in the Egyptian language: and it is further to be observed, that the Egyptians had a king called Remphis, the same with Apis; and this may be the reason why the Septuagint interpreters, who interpreted for Ptolomy, king of Egypt, put Rephan, which Stephen calls Remphan, instead of Chiun, which they were better acquainted with, since they both signify the same deity, and the same star; and which also was the star of the Israelites, called by them because supposed to have the government of the sabbath day, and therefore fitly called the “star of your god”.
The Six-Pointed Star is engraved on the Talisman of Saturn which is used in ritual magic TALISMAN OF SATURN;
“On the first face is engraved…a pentagram or a star with five points. On the other side is engraved a bull’s head enclosed in a SIX-POINTED STAR, and surrounded by letters composing the name REMPHA, THE PLANETARY GENIUS OF SATURN, according to the alphabet of the Magi.”
Saturn has also been associated with Satan and this, for numerous reasons. First, many authors argue that the word Satan is derived from the word Saturn. Second, Saturn is associated with the color black as well as Satan. Third, Ancients considered Saturn to be the farthest planet from the sun.
At anyrate Moloch, Chiun and Remphan are all names for the star god, Saturn, whose symbol is a six pointed star formed by two triangles. Saturn was the supreme god of the Chaldeans.
So Mo, Chiun, Rephan, or Remphan, and Remphis, all are the same with the Serapis of the Egyptians, and the calf of the Israelites; and which idolatry was introduced on account of Joseph, who interpreted the dream of Pharaoh’s kine, and provided for the Egyptians in the years of plenty against the years of famine, and was worshipped under the ox with a bushel on his head.
