Wrong. The first is conflated with the second (but the text does not go away and the prohibition against idols is right there)and the tenth is broken into two parts and we’re not the only group to do that.
Then the question is WHY? Why were the first two commandments condensed into one? And the tenth broken into two parts? If the second was made part of the first, then it would be necessary for another to be split in order to end up with ten. But why merge the first and second? I’ll trust your reasoning on this..maybe..if it’s good..:)
