Luke 9:29

And as he prayed, the fashion of his countenance was altered, and his raiment was white and glistering.

As he was praying, the appearance of his face was altered, and his clothing became white and dazzling.

And as he was praying, the fashion of his countenance was altered, and his raiment `became' white `and' dazzling.

and it came to pass, in his praying, the appearance of his face became altered, and his garment white -- sparkling.

And as He was praying, the appearance of His face changed, and His clothes became radiantly white.
