Satan is spoken of as walking up and down in the midst of the stones of fire.

         Ezekiel 28:14 "You were the anointed cherub who covers; I established you; You were on the holy mountain of God; You walked back and forth in the midst of fiery stones."

                  Fire is often used to speak of the presence of Jehovah: the burning bush, sacrificial fire, fire of incense, pillar of fire.

Hebrews 12:29 "For our God is a consuming fire."
