You know....there is another way to understand that verse that has nothing at all to do with snake worship, or the worship of false gods...
Have you ever had a look at the verse and took it to be talking about something in the "heaven" that it actually says it's talking about?
Im talking about the stars in the night sky.....or rather the constellations....the way people have come up with ways to group bunches of stars together in sections like "Orion and Taurus" etc.....
