I covered much of that in post #110.
“The Ten Commandments are shorthand for Leviticus.”
Where are you getting that from?
The Bible. They are one sentence summaries of major sections of Leviticus, which goes into far, far more detail about each of the ten commandments.
As Moses wrote the first five books, wrote Leviticus, and also took the tablets down from Sinai after God had etched them, if you compare what’s discussed in Leviticus you will see it the 10 Commandments are a concise summary of everything discussed in detail, in Levticus. It isn’t a surprise. It shouldn’t be.
