'Lightning' in the Bible

As He was praying, the appearance of His face became different [actually transformed], and His clothing became white and flashing with the brilliance of lightning.

He said to them, “I watched Satan fall from heaven like [a flash of] lightning.

For just like the lightning, when it flashes out of one part of the sky, gives light to the other part of the sky, so [visible] will the Son of Man be in His day.
