About the original and temples in general, why would God care how you organized some rocks?
He certainly gave very specific instructions about the container that held the tables of the covenant, though. Didn’t He?
When God ordains something He usually wants it done in a very particular way.
God was very particular about how He was to be approached. There are chapters and chapters of instructions about the exact details of the Tabernacle and the later Temple, and how they were to be built. Also rules and rules about sacrifices, and how they were to be done, down to what the priests were to wear, clean/unclean rules, etc. Why? He says because He is holy. You don’t just go up to Him as though He is just anybody.
Now we approach him through Christ.
