Moses as we know it was the prophet of God that was honored with a close relationship with the creator. He is the early representation of the Son of God Jesus. Moses was assigned by God to be the deliverer of His people Israel. Jesus was sent by His Father the creator to be the deliverer of all mankind from the punishment of sin the Eternal death.

Thru the Power of God the Father Moses was able to save Israel from death from the hands of the Pharaoh!
Jesus the Son of God (HASHEM) was able to save us from hell by dying on the cross.

The two tablets of stone is the torah. each Aramic letter has different words. that corresponds to the secret of the power of the 10 commandments.

The stone tablet was then placed inside the ark of the covenant with the TORAH... this 2 most powerful thing that is represented by the tablet of stone serves as the energy conductor of the Ark of the covenant.
the Light of the creator was placed on the tablets of the torah ( the law). This is the reason that the face of Moses shown brighter like the sun, because he shares the energy the stone tablet is producing.
