Fire is a symbol of the Divine Presence of Adonai. In the bush that didn’t burn, Moshe encountered the presence of Ehyeh Asher Ehyeh. The presence of Ehyeh Asher Ehyeh was in the column of fire that led the Israelites during the night as they trekked through the wilderness. When Adonai gave His Torah, the mountain was covered in smoke and fire.
"Your eyes will see Jerusalem: A tent which will not be folded; its stakes will never be pulled up" (Isaiah 33:20).
