'Lightning' in the Bible

{And} on the third day, when it was morning, there was thunder and lightning, and a heavy cloud over the mountain and a very loud ram's horn sound, and all the people who [were] in the camp trembled.

And all the people [were] seeing the thunder and the lightning and the sound of the ram's horn and the mountain smoking, and the people saw, and they trembled, and they stood at a distance.
