Lev. 9:24 and 10:2 : mention fire from regarding (/ conceptual proximity of) faces / surfaces of the true Deity. So, fire seems to be near, at least conceptually, to the true Deity.
Some angels can be messengers of the true Deity. Some entities can be His personal servants or attendants. In Psalm 104:4, the Hebrew word MEShRThIU seems to be used in other forms to describe the relationship of what Joseph was to Potipher and what Joshua was to Moses. So there seems to be a nearness. And they seem related to a fire flaming/flashing (ASh LEHET). This would be congruent with Leviticus 9:24 and 10:2, that they can be nearer to the true Deity, and fire came from regarding faces / surfaces of the true Deity, so they are near, or possibly in fire.
There are creatures that move about in various phases of matter. There are moles and worms and others that move in solids (dirt/ground/earth). There are fish and jellyfish and else that move and live in liquid (waters/seas/rivers/ponds/aquarium tanks). There are birds and humans and else that move and live in gases (air). But what about creatures that could move and live in fire, or plasma or lightning (/ electrical arcs)? Could some angels and/or other entities be of this kind?
In Judges 13:20, an angel went up in a blade or flame of the altar. And in Exodus 3:2, an angel of the true Deity was in a flame or blade of fire. Shadrach, Meshach, and Abednego were thrown into a fiery furnace and were able to survive and walk around in it, with a fourth entity there. So are there entities that were created to have a natural environment of fire? Are they adapted to live in plasma? If so, how?
In the Book of Enoch Section 2 chapters 43 and 44, some stars and lightnings are related. Possibly some stars become lightnings and cannot part with their new forms. How do they relate to electromagnetism?
Are some entities like moles, in that moles burrow in the earth, but they still need air; so can they live in fire but still need air? Or do they not? Or some do and some don't? How could something live in plasma as an environment?
