"You shall not make for yourself a graven 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; you shall not bow down to them or serve them; for I The Lord your God am a jealous God, visiting the iniquity of the fathers upon the children to the third and the fourth generation of those who hate Me, but showing steadfast love to thousands of those who love Me and keep My Commandments." (Exodus 20:4-6 RSV)
They are both seconds. They are both binary statements separated by punctuation.
The first commandment already covers worshiping other gods
See that is the problem, In the original Hebrew/ Aramaic there is no punctuation.
Second, you are trying to draw a parallel between a man made document and a divinely inspired text.
Third and this is the big one (I noticed that you ignored it completely) God very clearly directed the construction of both the Ark of the Covenant and the Bronze serpent. The Bronze serpent was only ordered to be destroyed after the the Israelites began to worship it as a false god. The parallel you ignored was the construction of the Golden calf. and the direction of God to destroy that.
Dang those pesky facts
I alwas thought that this just ment that God was exempt from his own rules. Thou shall not kill (he does it all the time. Thou shall not commit adultery (Mary's pregnancy and all). Neighbor's wife etc.
If you are aware of an original copy of Deuteronomy in Hebrew or Aramaic, I would love to see it and you will be famous. Most of what we have dates to after 100 AD. Neither Hebrew nor Aramaic is known to have existed at the time of Moses. How you know of the punctuation of an unwritten language is a mystery.
