They are:
Deuteronomy 5:2-5
The LORD our God made a covenant with us at Horeb. The LORD did not make this covenant with our fathers, but with us, with all those of us alive here today.
But for its moral aspects, they also reveal God's nature.
Paul actually addresses this topic. Idols are meaningless. It is idolatry that is a sin (anything, even one's theology, can be an idol).
Most of the time ionoclastism on these types of forums is nothing but hypocrisy. The iconoclast is quick to condemn people having a representation of Christ or a cross on a necklace or a fish on their bumper. But consider the commandment-
"You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth."
These iconoclasts often have facebook accounts with pictures of themselves, perhaps photographs at home of their families, of kids and grandchildren, maybe a landscape painting.
For us, the principle is against idolatry. This was expressed to the Jew via the Law in a very specific sense - no images of things in heaven, earth, seas....nothing.
An honest iconoclast would probably not even have an online presence so as not to violate the command. Historically Iconoclastism had no images.
