'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.

And he said unto them, I beheld Satan as lightning fall from heaven.

For as the lightning, that lighteneth out of the one part under heaven, shineth unto the other part under heaven; so shall also the Son of man be in his day.

At this they were in great perplexity, when suddenly there stood by them two men whose raiment flashed like lightning.
