TSK · Exodus 24:17

The angel of the LORD appeared to him in a flame of fire from within a bush. He looked– and the bush was ablaze with fire, but it was not being consumed!

Now Mount Sinai was completely covered with smoke because the LORD had descended on it in fire, and its smoke went up like the smoke of a great furnace, and the whole mountain shook violently.

From heaven he spoke to you in order to teach you, and on earth he showed you his great fire from which you also heard his words.

From the brightness in front of him came coals of fire.

like the appearance of a rainbow in the clouds after the rain. This was the appearance of the surrounding brilliant light; it looked like the glory of the LORD. When I saw it, I threw myself face down, and I heard a voice speaking.

His brightness will be as lightning; a two-pronged lightning bolt flashing from his hand. This is the outward display of his power.

For our God is indeed a devouring fire.
