Exodus 20 18
When the people saw the thunder and lightning and heard the trumpet and saw the mountain in smoke, they trembled with fear. They stayed at a distance
I remember a clue saying something about watching from a distance, or something like that.
I think maybe 20/18 might have to do with a volcano in Australia.
I think possibly in the south because of the CRUX/Southern Cross clues.

Time will tell I guess.
