Jamieson Fausset Brown Commentary
Verse 29. as he prayed, the fashion, &c.–Before He cried He was answered, and while He was yet speaking He was heard. Blessed interruption to prayer this! Thanks to God, transfiguring manifestations are not quite strangers here. Ofttimes in the deepest depths, out of groanings which cannot be uttered, God’s dear children are suddenly transported to a kind of heaven upon earth, and their soul is made as the chariots of Amminadab. Their prayers fetch down such light, strength, holy gladness, as make their face to shine, putting a kind of celestial radiance upon it (2Co 3:18; Ex 34:29-35).
raiment white, &c.–Matthew says, “His face did shine as the sun” (Mt 17:2), and Mark says (Mr 9:3), “His raiment became shining, exceeding white as snow, so as no fuller on earth can white them” (Mr 9:3). The light, then, it would seem, shone not upon Him from without, but out of Him from within; He was all irradiated, was in one blaze of celestial glory. What a contrast to that “visage more marred than men, and His form than the sons of men!” (Isa 52:14).
Philip Doddridge NT
And as he was praying, it came to pass that he was suddenly, in a most glorious manner, transfigured in their presence; and the form of his countenance was changed, {so that} his face shone with a brightness like that of the sun; and his whole body was clothed with such a luster as shone through his raiment, insomuch that the appearance of it was all white and dazzling, shining so exceedingly, that it seemed as white as snow, [yea] as resplendent as the light itself, to so great a degree as no fuller on earth could whiten it. Such a glory did God confer on his Son, as an earnest of that in which he was finally to appear; and he permitted these his servants to see it, that they might not be offended at those scenes of deep abasement in which they were shortly to attend him. (Compare Mt 26:37.)
