He was Transfigured Before Them

"...and He was transfigured before them. His face shone like the sun, and His clothes became as white as the light" (Matthew 17:2; NKJV)

To transform (literally or figuratively): KJV - change, transfigure, transform (Strong’s)

To change into another form, to transfigure, transform: Of Christ, his appearance was changed (A.V., he was transfigured), i.e., was resplendent with a divine brightness, MATT 17:2; MK 9:2; LK 9:29. Used of Christians: we are transformed into the same image (of consummate excellence that shines in Christ), reproduce the same image, 2 COR 3:18 (Thayer’s)

“To change into another form" (meta, implying change, and morphe, "form” Is used in the passive voice (a) of Christ's "transfiguration," MATT 17:2; MK 9:2 Luke (in 9:29) avoids this term, which might have suggested to Gentile readers the metamorphoses of heathen gods, and uses the phrase egeneto heteron, "was altered", lit., "became (ginomai) different (heteros)“ (Vine’s).

“This glory was not the light of heaven falling upon Him from above…That was the glory of His own face, of His own Person, shining through the veil that had hidden it, until the very raiment of His humanity sparkled and glistened and flashed with the splendor of light and snow and lightning. The transfiguration was effected, not by glory falling on Him, but by inherent glory flashing forth" (G. Campbell Morgan, The Crises of the Christ, p. 227-28).
