'Flashing' in the Bible

As I watched, I noticed a windstorm coming from the north -- an enormous cloud, with lightning flashing, such that bright light rimmed it and came from it like glowing amber from the middle of a fire.

In the middle of the living beings was something like burning coals of fire or like torches. It moved back and forth among the living beings. It was bright, and lightning was flashing out of the fire.
