“Mount Sinai was covered with smoke, because Adonai descended on it in fire. The smoke billowed up from it like smoke from a furnace, and the whole mountain trembled violently.” Exodus 19:18
Moses encounters God at the burning bush in Sinai at the mountain of God. He sees a burning bush and speaks to God. Moses is told to go back to Egypt and bring the Israelites to the same place. And now at the same place that Moses encountered God all the Israelites encounter the Divine. Everyone, you do not need to be a priest or a prophet to encounter God, no need for mediation, we all face God equally.
