You are not following the conversation - the post I replied to was in response to a poster claiming the Ten Commandments was only spoken not written, I posted scripture to show otherwise. Everything else you're claiming is conjecture and strawman.
The first covenant between God and Israel was based on the spoken word!
Exodus 20 to Exodus 24, is the foundational covenant.
The tablets of stone were simply a replication of the initial covenant in Exodus 24.
