'Flashing' 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.

For just as the lightning shines forth, flashing from [one place] under heaven to [another place] under heaven, so the Son of Man will be in his day.

at midday, O King, I saw on the way a light from heaven surpassing the brightness of the sun, shining all around me and those who were traveling with me.
