Amos, also referenced in Acts, is speaking about this star as going after other gods, but Jesus says only He is the bright morning star and Him alone is who we need to be worshipping. The six-pointed star serves as a magical sign of the gods Moloch and Chiun and also a sign of Judaism that even today go after other gods/idols. I don't think to many know the history of the six sided star as I had to just now look it up.
Amos 5:26 But ye have borne the tabernacle of your Moloch and Chiun your images, the star of your god, which ye made to yourselves.
Amo 5:27 Therefore will I cause you to go into captivity beyond Damascus, saith the LORD, whose name is The God of hosts.
Act 7:43 Yea, ye took up the tabernacle of Moloch, and the star of your god Remphan, figures which ye made to worship them: and I will carry you away beyond Babylon.
