They worship a false god, some say a moon god.
I am the LORD thy God, who brought thee out of the land of Egypt, out of the house of bondage. Thou shalt have no other gods before Me.
Thou shalt not bow down unto them, nor serve them; for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children, and upon the third and upon the fourth generation of them that hate Me.
Deuteronomy Chapter 5 kind of said it all IMO.
Warning! This is a high-volume ping list.
